Cheezburger Network of sites sucks.

They literally suck. They suck in many good images found in all parts of the web like a black hole, and give no credit to anyone if they can possibly help it.  They can't be bothered.  They're too busy counting the money they make from everyone else's work.

edit- I've heard a couple of comments that blame the submitters to their sites, and not Cheezburger themselves. Well, who put together the way their sites work? They can try to wash their hands of wrong-doing, but it's their system, and they know the end result will be lots of anonymous images thrown into the furnace of their giant money making machine.
And this is at least the third time this has happened, after promises made on their end.

Edit #2- Someone else wrote about the same thing happening to them-
