Someone kind of mentioned it, but use of Blizzard's logo is the violation of copyright. Just crediting Blizzard for their logo doesn't forgive the copyright infringement. Your works are your works, but you can't take someone else's logo and stamp it on your work like it's a seal of approval. That's where the infringement comes in. That's Blizzard's seal and they are the only ones legally allowed to use it unless you have expressed written permission from Blizzard. Not harping on you, just trying to explain why it was removed once and still can be removed.
just put "World of warcraft logo and original draenei and blood elves caracters are copyrighted by blizzard"... maybe is that the probelm... or.. maybe it' just some envious idiot reporting you... in both cases, it should work.
