In its defense Craigslist successfully used Section 230 of the US Communications Decency Act (CDA), which states that websites cannot be held liable for the actions of their users. Craigslist also successfully challenged
243-416: A 1995 barebone design, which became its most recognizable feature. Over the years Craigslist had become a very popular online destination for arranging for dates and sex . The personals section allows for postings that are for "strictly platonic", "dating/romance", and "casual encounters". The site was considered particularly useful by lesbians and gay men seeking to make connections, because of
324-631: A 2017 FOSTA amendment to the CDA , which created an exception allowing legal actions against a platform, if its users violate federal sex-trafficking laws (see Dart v. Craigslist, Inc. ). In July 2005, the San Francisco Chronicle criticized Craigslist for allowing ads from dog breeders, stating that this could encourage the over-breeding and irresponsible selling of pit bulls in the Bay Area. According to Craigslist's terms of service ,

By July 2007, when the first "The State of the Map" (SotM) conference was held, there were 9,000 registered users. In October 2007, OpenStreetMap completed the import of a US Census TIGER road dataset. In December 2007, Oxford University became the first major organisation to use OpenStreetMap data on their main website. Ways to import and export data have continued to grow – by 2008,
648-528: A comprehensive security assessment of the OSM data model has yet to take place. There have been several high-profile incidents of vandalism and other errors in OSM: Players of Pokémon Go have been known to vandalize OSM, one of the game's map data sources, to manipulate gameplay. However, this vandalism is casual, rarely sustained, and it is predictable based on the mechanics of the game. The project has
729-465: A conventional GIS or CAD system. It is a topological data structure without the formal concept of a layer, allowing thematically diverse data to commingle and interconnect. A map feature or element is modelled as one of three geometric primitives : OSM manages metadata as a folksonomy . Each element contains key-value pairs , called tags , that identify and describe the feature. A recommended ontology of map features (the meaning of tags )
810-539: A counter-suit in May 2008 to "remedy the substantial and ongoing harm to fair competition" that Craigslist claimed was constituted by eBay's actions as Craigslist shareholders; the company claimed that it had used its minority stake to gain access to confidential information, which it then used as part of its competing service Kijiji . On June 19, 2015, eBay Inc. announced that it would divest its stake back to Craigslist for an undisclosed amount, and settle its litigation with
891-410: A geographically diverse user-base, due to emphasis of local knowledge and "on-the-ground" situation in the process of data collection. Many early contributors were cyclists who survey with and for bicyclists, charting cycleroutes and navigable trails . Others are GIS professionals.

Mapathon competition events are also held by local OpenStreetMap teams and by non-profit organisations and local governments to map a particular area. The availability of aerial photography and other data from commercial and government sources has added important sources of data for manual editing and automated imports. Special processes are in place to handle automated imports and avoid legal and technical problems. Ground surveys are performed by

OpenStreetMap uses its own topology to store geographical features which can then be exported into other GIS file formats . The OpenStreetMap website itself is an online map , geodata search engine and editor. OpenStreetMap was created by Steve Coast in response to
1296-689: A staff of 28 people. By 2019 this number grew to 50 people. In that year alone the company made more than $ 1 billion in revenue, while charging only ca.5 US$ for most ads (the exact price depends on the type of ad and service/property location). In December 2006, at the UBS Global Media Conference in New York, Craigslist CEO Jim Buckmaster told Wall Street analysts that Craigslist had little interest in maximizing profit, and instead preferred to help users find cars, apartments, jobs and dates. Craigslist's main source of revenue
1377-472: A study conducted in 2011, only 38% of members carried out at least one edit and only 5% of members created more than 1000 nodes. Most members are in Europe (72%). According to another study, when a competing maps platform is launched, OSM attracts fewer new contributors and pre-existing contributors increase their level of contribution possibly driven by their ideological attachment to the platform. Overall, there
1458-747: A team which revises the map based on GPS traces and feedback from its drivers. In eight Southeast Asian countries, Grab has contributed more than 800,000 kilometres (500,000 mi) of roads based on drivers' GPS traces, including many narrow alleyways that are missing from other mapping platforms. eCourier also contributes its drivers' GPS traces to OSM. According to a study, about 17% of road kilometers were last touched by corporate teams in March 2020. The top 13 corporate contributors during 2014–2020 include Apple, Kaart, Amazon, Facebook, Mapbox, Digital Egypt, Grab, Microsoft, Telenav, Developmentseed, Uber, Lightcyphers and Lyft. According to OpenStreetMap Statistics,
1539-646: A user flagging system to report illegal and inappropriate postings. Flagging does not require account login or registration, and can be done anonymously by anyone. Postings are subject to automated removal when a certain number of users flag them. The number of flags required for a posting's removal is dynamically variable and remains unknown to all but Craigslist staff. Some users allege that flagging may also occur as acts of vandalism by groups of individuals at different ISPs, but no evidence of this has ever been shown. Flagging can also alert Craigslist staff to blocks of ads requiring manual oversight or removal. Flagging
1620-567: Is maintained on a wiki . New tagging schemes can always be proposed by a popular vote of a written proposal in OpenStreetMap wiki, however, there is no requirement to follow this process. There are over 89 million different kinds of tags in use as of June 2017. The OpenStreetMap data primitives are stored and processed in different formats. OpenStreetMap server uses PostgreSQL database , with one table for each data primitive, with individual objects stored as rows . The data structure

Craigslist includes a barter option in its "for sale" section. This growing trade economy has been documented on the television program Barter Kings and the blog one red paperclip . From its earliest days Craigslist faced criticism for allowing illegal/unethical activities and for poor protection of buyers and sellers. Some well-recognized types of illegal activities comprise: counterfeit goods , advanced fee fraud and buyer-seller collusion . In "counterfeit goods" scam,

This decision came after allegations by several U.S. states that the erotic services ads were being used for prostitution. On September 4, 2010, Craigslist closed the adult services section of its website in the United States. The site initially replaced the adult services page link with
3159-442: The "censored" label and its dead link to adult services were completely removed. Craigslist announced on September 15, 2010, that it had closed its adult services in the United States; however, it defended its right to carry such ads. Free speech and some sex crime victim advocates criticized the removal of the section, saying that it threatened free speech and that it diminished law enforcement's ability to track criminals. However,

On December 19 , 2010, after pressure from Ottawa and several provinces, Craigslist closed 'Erotic Services' and 'Adult Gigs' from its Canadian website, even though prostitution was not itself illegal in Canada at the time. When the Fight Online Sex Trafficking Act was signed into law on April 11, 2018, Craigslist chose to close its "Personals" section within all US domains to avoid civil lawsuits. About their decision, Craigslist stated "Any tool or service can be misused. We can't take such risk without jeopardizing all our other services." Craigslist has

The Swedish luxury marketplace website Jameslist.com received a lawsuit filed on July 11, 2012, which among unspecified damages also asked for a complete shutdown of Jameslist.com As a consequence, the young company was forced to rename to JamesEdition . As of 2012, mashup sites such as padmapper.com and housingmaps.com were overlaying Craigslist data with Google Maps and adding their own search filters to improve usability. In June 2012, Craigslist changed its terms of service to disallow

Changesets submitted through editors and the OSM API immediately enter the database and are quickly published for reuse, without going through peer review beforehand. The API only validates changes for basic well-formedness, but not for topological or logical consistency or for adherence to community norms. As a crowdsourced project, OSM is susceptible to several forms of data vandalism , including copyright infringement, graffiti, and spam. Overall, vandalism accounts for an estimated 0.2% of edits to OSM, which

Chief among these were Foursquare and Craigslist , which adopted OpenStreetMap, and Apple , which ended a contract with Google and launched a self-built mapping platform using TomTom and OpenStreetMap data. The OSM project aims to collect data about stationary objects throughout
4374-441: The list was a good way to reach people with the skills they were looking for. This led to the addition of a jobs category. User demand for more categories caused the list of categories to grow. The initial technology encountered some limits, so by June 1995 Majordomo had been installed, and the mailing list "Craigslist" resumed operations. Community members started asking for a web interface. Newmark registered "craigslist.org", and

Brian Carver, attorney and assistant professor at UC Berkeley, said that legal threats could have a chilling effect on online expression. "If you impose liability on Craigslist, YouTube and Facebook for anything their users do, then they're not going to take chances. It would likely result in the takedown of what might otherwise be perfectly legitimate free expression." On September 8 , 2010,

Craigslist said that there is some indication that those who posted ads in the adult services section are posting elsewhere. Sex ads had cost $ 10 initially and it was estimated they would have brought in $ 44 million in 2010 had they continued. In the four months following the closure, monthly revenue from sex ads on six other sites (primarily Backpage ) increased from $ 2.1 to $ 3.1 million, partly due to price increases. The company has tried to fight prostitution and sex trafficking, and in 2015, Craig Newmark received an award from
