Unless you are an admin on the wiki, you cannot block users. Even if you do, they will be block from that wiki only. If the users in question have done this to multiple users on a particular wiki, you can contact the admins for that wiki and ask them to consider blocking the users; but they are not required to. If the users in question have done this to you (and/or multiple users) accross multiple wikis, you can consider reporting them to VSTF.
