I'm not sure anyone has said anything terrible or untrue about it?
There was a problem here with new people being attacked, particularly if they talked about the comic or tried to defend someone who they didn't know. I was a part of it. We were hostile and rude, but we were used to it. We expected new members to lurk for a long time before they gave input, and when one of them offended, it resulted in people piling on. The group realized that they had out grown this space. That is why people left, not because they were bad people but because there had been talk of making a separate forum for some time, and it had gotten to the point, since registration was finally unlocked, that it was clear that a large group of us might be better elsewhere.
Pocket Jury is a fairly closed group of people, by design I would argue. There is nothing wrong with that, but if you don't fit in with that group of people, then you don't fit in with them, if you do then it might be an excellent forum for you. If you post a lot in the music section here you might be interested, but if that is the case you also have seen Tommy's recent post advertising it. If people are on this forum because they like and want to talk about the comic, then PJ is not the place for them.
