It is almost impossible to report someone for being rude if they are the admin of that wiki. In fact, even if they are rude and not an admin but the admin of the wiki chooses not to discipline it is the same deal.

Usually leaving the wiki is the best practice; if you can't work it out civilly. I have left one wiki due to a rude admin and once just cause I personality clashed with an admin (but we weren't rude/badly behaving) just wasn't worth the stress.

Now if they followed you to other wikis or community central then it could be something the staff might intervene on.
