I don't think so. He took a few months off, tried to come back and made a really innocuous post, about his garden or something, and in no time at all, the post was being trolled and downvoted into oblivion. I talked to him a bit by email, he is just done. I don't blame him, it is like roulette to post here these days for anyone, and if you cross the wrong asshat once it is pretty much over.
