Thread:Project:Support desk/Blocking profanity, restricting external links by user groups and blocking edits by user age?/reply

To block profanity and external links, I would suggest using some simple AbuseFilters. If you're unfamiliar with AbuseFilter, I'd be able to give you some basic codes for it once you set it up on your wiki, which would hopefully get the job done. Abuse Filters also have associated logs that list infractions of the filter.

As for blocking age, I personally don't know which MediaWiki extensions there are that can prevent user sign-up to certain age. I know Wikia has it, but I don't know if there is an extension for it that you could use. Someone else would have to find that for you. I hope that AbuseFilter will meet some of your needs though. :)
