Right, before the threat of legal action and all, the offending pictures have gone.
But once again, you should not have gone and done this behind my and every other admin's back. It would already have been unfortunate if you had been the artist in question, but you had no personal stake in the matter, so really it's just mutiny.
I have blocked you for two weeks, with all due respect, to impress upon you the seriousness of this situation. If you're willing to apologize, the circumstances of your ban mean you should still ve able to reply to message threads on your talk page, so do so here, and I'm quite willing to lift the ban early.
While I agree that DoggoRoboto should have talked to an administrator about this first, I'm not so sure it should warrant a block, even if it is for only two weeks. In my opinion, there's nothing particularly bad about reporting a possible breach in copyright - the original artist did want his work removed, after all, so he had a justifiable reason for it. It's your decision, of course, Scrooge MacDuck, but I feel that DoggoRoboto meant well when he reported this, even if it was done without administrative knowledge.
Okay, you two have convinced me. Though I'd still like to see an apology from DoggoRoboto in the not-too-distant future.
The thing is, it's not even just going behind administrators' back and against their instructions; it's that DoggoRoboto did so to snitch to WikiaStaff about a potential copyright problem, which Wikis should only do if they have a death wish, because, having a vested interest in not being sued, Staff will tend to stray on the side of paranoia in such matters.
Problems such as these should always be handled within the Wiki, especially when it's just an author going She-Who-Must-Not-Be-Named on us without proper justification (and that is what happened here; Mr Hillemarcher just doesn't like us documenting his work for some reason, but he has no more of a claim that we're in breach of copyright than Disney does for most every other picture on here; that is to say, a not-wholly-unreasonable claim, but of a sort that we can't start listening to or we'll have to delete every damn picture we have).
Yes, I agree that matters such as these should be handled without involving Wikia Staff. It would have been best, I think, for everyone involved to have simply discussed the matter civilly until a solution could be reached, before matters got out of hand.
