the article on the Renaissance does not give sufficient credit to Christianity, that Wikipedia articles apparently prefer to use non-American spellings even though most users are American, that the article on American activities in the Philippines has a distinctly anti-American bias, and that attempts to include pro-Christian or pro-American views are removed very quickly. Schlafly also claimed that Wikipedia's allowance of both Common Era and Anno Domini notation was anti-Christian bias. Licensing of content Conservapedia allows users to "use any of the content on this site with or without attribution". The copyright policy also states: "This license is revocable only in very rare instances of self-defense, such as protecting continued use by Conservapedia editors or other licensees." It also does not permit "unauthorized mirroring". Wikipedia co-founder Jimmy Wales has raised concerns about the fact that the project is not licensed under the GNU Free Documentation License (GFDL) or a similar copyleft license, stating that "[p]eople who contribute [to Conservapedia] are giving them full control of the content, which may lead to unpleasant results." Vandalism The site has stated that it prohibits unregistered users from editing entries due to concerns over vandalism, disruption or defamation. Brian Macdonald, a Conservapedia editor, commented that vandalism was intended to "cause people to say, 'That Conservapedia is just wacko.'" According to Stephanie Simon of the Los Angeles Times, Macdonald spent many hours every day reverting "malicious editing". Vandals had inserted "errors, pornographic photos and satire". For example, U.S. Attorney General Alberto R. Gonzales was said to be "a strong supporter of torture as a law enforcement tool for use against Democrats and third world inhabitants". Other editorial policies Conservapedia states on its "Manual of Style" page that "American English spellings are preferred but Commonwealth spellings, for de novo or otherwise well-maintained articles are welcome." It prefers that articles about the United Kingdom use British English, while articles about the United States use American English, to resolve editorial disputes. Initially, Schlafly and other Conservapedia editors considered Wikipedia's policy allowing British English spelling to be anti-American bias. The "Conservapedia Commandments" require edits to be "family-friendly, clean, concise, and without gossip or foul language" and that users make mostly quality edits to articles. Accounts that engage in what the site considers "unproductive activity, such as 90% talk and only 10% quality edits" may be blocked. The commandments also cite United States Code 18 USC § 1470 as justification
