If anything comes out of this situation, I would hope it would be discussion as to the moderation of the board. It's not entirely clear what powers mod and admins have and how they can use them. Like most other boards, it should be clear and transparent when someone has received a warning, how many they can receive before being banned temporarily and why they would then receive a permanent ban.
Otherwise, rules are enforced unfairly and unequally. Many members have said far worse and personally offensive things while I've been a member and they were never banned or warned. That's purely down to favouritism and friendships and that's understandable given the nature of the community here. But a moderators role is to apply the rules fairly and if they are abusing their power then the board isn't being moderated properly.
A moderators role shouldn't to meddle in or stymie debates. Message boards are places where discussions get heated and people have differing views that often come down to a back and forth as to who said what. A moderator should apply the rules and issue warnings and bans when people are being really personally offensive and aggressive towards another member, not just when it's something trivial and there's a dislike for that person. If you found what Gawain said to be offensive Carlos, then that's fair. But objectively speaking, what he said is pretty much common place. People are called bitter or drama queens in all walks of life. Banning him for that screams of an abuse of power. If his PM was also offensive, it should be made clear what constitutes "offensive behaviour" that breaches a board rule. Not just what is offensive to you because you have power.
I feel there should be a forum discussion as to the rules and how they are to be applied to ensure some level of fairness, transparency and accountability for us plebian members and the moderators/administrators alike.
