There has been a lot of vandalism on wikibooks recently, where the user posted a long list of links to recently edited pages. I would suggest a "blacklist" of links: If a user adds links (e.g. to dubious Chinese or Japanese translation service sites) that appear in a blacklist (maintained by admins), then his edit shall not be accepted. Optionally, the system may ask for removal of these links before accepting the contribution (preferably without listing, which of the links are on the blacklist). This should slow down systematic vandals, who want to spread certain web addresses.
In fact, this feature already exists! I had no idea how it worked, but hunting around a bit (actually, quite a lot, but the customised message [[en:MediaWiki:Spamprotectiontext]] finally gave me the lead) I see that it is administered centrally, at [[meta:Spam blacklist]]. By the looks of it, you should be able to request additions to the regex at that article's talk page, and have them come into effect Wikimedia-wide.
Thanks. This is just what I was looking for.
