I just got involved in undoing a crapload of unwanted edits on Wikitubia; Fawful's Minion's page. There were several newbie users, which I believed to be scammers/maybe hackers, and I informed the admin there immediately! No response, and I couldn't undo them; hell, even "Restrictions" were removed. So I undid the edits myself, and had to type the background from memory. I hope the legit users would restore the page eventually. That was quite a fright, knowing there could be hackers out there! And I also listed them on my Message Board as well. Basically it was just a bunch of Breaking Bad/Mexican/Better Call, Saul bullshit.
Actually yes he was busy, he did realize the problem, albeit late. I gave him a list of suspects even, and he verified that not all the users were responsible; I apologized to each one, too. But yeah, I fixed the problem as best I could, and I'll alert him the next time it happens, he'll be more vigilante next time.
