Hard to say for sure, especially with everything gone.

A quick summary of the story is that PDT was (at least) his second incarnation. He walked close to the line (you can agree or disagree with the line, I disagree with plenty myself), both before and after. Once he decided to "leave", I expect he didn't worry so much about not stepping over the line. Without seeing what he posted, we will never know, but I expect he knew what would happen.

It would not shock me if after things have cooled, he is given the opportunity to return. Whether he will take it or not, I don't know.

I don't need to defend Mr. JTB, but I will anyway. He's about the most straight-up guy on the board, and what many would call a success story besides. If he posts on your thread, you should feel pretty good about it. And he is not a huge fan of many actions the mods have taken at various times in the past few years.
