Vandalism has been reverted/deleted now. The accounts blocked as well. If there is something I missed, please let me know.

As far as deleting the edits from history, there is no way easy tool that does that currently. Staff have access to revision delete and suppress revision, but they don't use it on request typically. If you already sent the Special:Contact, it's worth seeing what they say if you already asked.

All the bad images are deleted at least. They appeal in Special:Log/delete and I'm not sure if that's a problem. Technically, as an admin you can "delete history edits" but it's not recommended to do so. It requires deleting and then undeleting the revisions you want to restore. It comes at a cost of "view X deleted edits" in page history every time you access it.

Lastly, I can't rename accounts nor am I able to change their avatar images :( It's often best to just ignore them and not worry about it. Trolls are everywhere and at some point every wiki has to deal with them. Good news wise, everything should be reverted and other than history, nothing should be left!
