MEpedia:Blacklists and whitelists

A blacklist is a list of words/phrases or websites which are not allowed. These terms or websites are typically only prevented from being used in certain ways, for example as page names.

A whitelist is a list of words/phrases or websites that are always allowed, even if they also match something on the blacklist.

Purpose
MEpedia mainly uses blacklists to prevent spam, for example to prevent links to websites often reported to be promoted by spammers, known malware websites, or to prevent vandalism such as using inappropriate terms to create content e.g. uploading pornography.

MEpedia uses a whitelist of trusted websites so that editors who link to these websites will not be prompted to fill out the MEpedia:CAPTCHA task when they save edits, which means newer editors using certain reliable websites do not have to continually answer a question every time they want to save their work.

Blacklists

 * MediaWiki:Pageimages-blacklist
 * MediaWiki:TitleBlacklist
 * Extension:SpamBlacklist is included with MediaWiki but not installed.
 * Further restrictions may be listed in LocalSettings.php, which is accessible to MEpedia:Developers only

Whitelists

 * MediaWiki:Captcha-addurl-whitelist for websites very likely to be used as references

Permissions
Changes to the blacklist and whitelist pages are restricted to administrators. Requests for changes can be made on the relevant talk pages.
