Question: In August 2007 Virgil Griffith, a Caltech computation and neural-systems graduate student, created a searchable database that linked changes made by anonymous Wikipedia editors to companies and organizations from which the changes were made. The database cross-referenced logs of Wikipedia edits with publicly available records pertaining to the internet IP addresses edits were made from. Griffith was motivated by the edits from the United States Congress, and wanted to see if others were similarly promoting themselves. The tool was designed to detect conflict of interest edits. Among his findings were that FBI computers were used to edit the FBI article in Wikipedia. Although the edits correlated with known FBI IP addresses, there was no proof that the changes actually came from a member or employee of the FBI, only that someone who had access to their network had edited the FBI article in Wikipedia. Wikipedia spokespersons received Griffith's "WikiScanner" positively, noting that it helped prevent conflicts of interest from influencing articles as well as increasing transparency and mitigating attempts to remove or distort relevant facts.

Question: There has been a football tournament at every Summer Olympic Games since 1900, except at the 1932 games in Los Angeles. Before the inception of the World Cup, the Olympics (especially during the 1920s) had the same status as the World Cup. Originally, the event was for amateurs only; however, since the 1984 Summer Olympics, professional players have been permitted, albeit with certain restrictions which prevent countries from fielding their strongest sides. The Olympic men's tournament is played at Under-23 level. In the past the Olympics have allowed a restricted number of over-age players per team. A women's tournament was added in 1996; in contrast to the men's event, full international sides without age restrictions play the women's Olympic tournament.
