The best you can do is to revert all edits made by User:WikiaBot on the wiki. Just append ?bot=1 at the end of the Special:Contributions/WikiaBot URL and hit all revert links. That will hide your edits from Recent Changes and the diffs.

Hopefully we were already using a template to insert youtube videos in articles so the script haven't touched them.
