Thread:Project:Support desk/bots attack, please help/reply (2)

Nuke would be the easiest, I think. I've been using it on my spam-trap wiki.

If you don't need a public wiki, though, you should just allow only those users who can provide legitimate content.

Otherwise, check out Extension:ConfirmEdit, especially Extension:QuestyCaptcha since it will require contributors to your wiki to be familiar with things particular to your wiki.
