People are really overblowing the whole deleted for copyright thing. Right now, I'm looking at two Mario Bros. level, a Dead Space level, a level that shows you how to make loads of copyrighted costumes (incl. Snake), a Metal Gear Solid level, a StarFox music level, a SAW level, and a Spirited Away music level, all on the first page.
The God of War level got deleted for violent content (you sacrifice people near the end), not for copyright violation.
