Well I don't disagree with you there.
I think it was "how" he stuck his neck out and had a conflicting opinion.
We all have our opinions and we all don't agree. That's certainly what makes a forum run or we'd often have nothing to talk about.
I don't know the details regarding Ghost's banning but generally speaking, when someone gets banned from GOT, it's usually due to posts that are directed towards an individual and abusive in nature. That or they're just on a constant windup with no real substance to the posts and not looking to contribute to any meaningful dialogue.
As a forum as a whole, we can only take so much of that before it becomes a detriment to the forum. Long time lurkers might reconsider registering and posting if they feel that someone's gonna have a go at them for anything they might have to say.
Just my two cents but I'm sure if you want details regarding recent bannage, you can PM one of the moderators and they can give you specifics.
