Hmm. The word in the HP comms was that the offending pic was not actually the Detention pic, but one depicting an adult Harry. And interestingly enough, there are still tons of HP slash and noncon floating around on LJ; heck; I went searching for pokeporn and found that's still hosted there, too. (No, I'm not into Pokemon porn; I just wanted to see if other comms were affected.)

It's a witchhunt, and it has nothing to do with age depiction or consent status or artistic merit.
