Funnyjunk, no; the oatmeal, yes.
I think this whole thing is pretty crazy, websites like funny junk or 9gag thrive of the reposting of others works usually without credit and always without consent.
I hope this goes royally tits up for both that lawyer and funnyjunk, for a multitude of reasons, both are terrible. (That is not to say I like Matthew inman at all, he acts like a total douchebag but does at least happen to be an innocent Vic I'm here)
