LMsA: If he doesn't comply
I have no idea if a countersuit is feasible or not. But if it was and they won, they wouldn't need to care if he complied or not. The verdict itself would be a direct kick in the pants. What could he do, at that point? Ignore it? Fine, everyone else could paper the internet with it and use it to embarrass him further. Or maybe he would make a post to his supporters, criticizing the verdict and making a show of promising not to comply? That would bring the news straight to the one remaining group that he really wishes wouldn't see it.
Then again, this seems to be the case with him over and over. His arrogance and plain old meanspiritedness have led him down a path of one bad decision after another. I don't really think it's possible for him to fix this anymore. The hole is too deep. His options are to keep digging until he disappears, or learn to wash dishes semi-competently and live on a shoestring.
