Someone's been spamming the English Wikipedia with the website "www.AnonTalk.com", often replacing the entire content on the targeted page (see links below). Since it's not actually linked, the ordinary URL blacklists don't catch it. (It's also not very effective as spam, but the blanking is annoying.) Bot use has been suggested, though not proven.

Just in case it is indeed a spambot, I'd like to suggest that "\b(?i:anontalk\.com)\b" be added to $wgCaptchaRegexes. It might also be worth adding the specific variants used by the vandal, such as "'''(?i:www\.anontalk\.com)'''", to $wgSpamRegex.

Actually, come to think of it, just adding "\b(?i:anontalk\.com)\b" to $wgSpamRegex wouldn't necessarily be that bad; anyone legitimately discussing that site can always write it as "anontalk DOT com" or something.
