Could be. I'm actually not all that outraged that they'd ask to remove a porn picture, but that they responded with a rather draconian measure of suspending all accounts of those artists (even RL and RPG accounts that weren't used to post art) without warning right away. For all their "clarifications" they never came out and set a no-explicit-porn rule (say all pictures that shows genitals of people involved in sexual activity or something), nor did they say to my knowledge that all explicit content with fictional older teenagers or characters that could just be perceived as under-18 is taboo, but remained rather vague of what they think is already "childporn" and what they see as "obscene", which is their prerogative of course and maybe they just want some maneuvering room to make the best of the situations when they do have to respond to pressure while overlooking other things that didn't get complaints, but if they are all fuzzy about what is allowed and what not, it's just not right to sanction a user this severely right away, IMO. A take down notice or even a temporary suspension of a specific account until the user has removed the TOS-violating content I can see on a first offense, but this seems OTT for the material in question, which is after all with fictional characters (rather than explicit photos of a real teenager) and not even obviously chan either, but looked to me just like a slightly manga-influenced drawing of an adult Harry.
