I suggest implementing a "mark as spam" button near each post on the forum. After a post has gathered x spam marks, someone on the team should get an email, suggesting the deletion of said post. The post itself might also be added to the email, in order to simplify the decision.

Just your typical last comment advertising, this time with patents.
https://trisquel.info/en/users/carlroscoe/track
Yes, even if the current trend is add-on list spamming with some last-comment-in-a-thread-with-links pepper, wiki spamming is relatively usual as well.
We have a wiki spammer!
