I think Libertas will be fine as long as he doesn't keep acting like the victim of some organised witchhunt.
It's funny you should say that, as I had him on ignore in both of his incarnations my only interaction with him was a fantasy politics case where he acted extraordinarily paranoid, as though he were being persecuted in a collaboration of all these separate people.
I did read a few of his recent stories, and found them amusing, but I think he has a very abrasive nature that does not seem to have mellowed. I don't remember why he was banned, and I'd prefer to see contributors who wish to return be given a chance to do so. But he certainly strikes me as someone who has not changed on a truly fundamental level.
