Sure, but in all fairness, I don't see how he could get away with this again, even if he wanted to.
DP pissed off almost the entire fandom with this stunt. Said fandom then dug into his pictures and compiled enough evidence to nail him to the wall and force a confession within hours of the scandal breaking. If he so much as traces one more pony in one more picture, within one day he'll have an army of angry fans ready to mount his arse on a stop sign and leave him to direct traffic.
My prediction: People are going to take his apology with a grain of salt (as they should), the art scene is going to be a bit rough for Neil for about half a year, but we won't see a repeat. Neil may be lazy and dumb, but he seems like a good enough human being underneath the whole lazy shithead thing. After this rough period, people will have moved on, and most of Neil's former fans will have come back to him. He lives, learns, and develops his art skills, business ethics, and self-preservation instinct while he's at it..
