Process for removing spam users

This came up over the weekend and I handled it (somewhat). There was a user that was confirmed and got an account created on the wiki. Their user page was then made an advertisement for some SMS related thing that had nothing to do with oVirt. On request, I deleted the page and blocked the user[1]. As I've done very little wiki administration in the past, I wanted to make sure that we have a consistent process in place for handling situations like this in the future. Any thoughts?
