Contact Management members via PMs and without solid proof, there's just no need to make a topic like this. I am 100% sure that tha bans were given because some people broke the rules.
Rules:
7) If you have a problem with someone contact them or a staff member in private, going over the forum posting accusations, especially with no hard evidence to back it up, will get you in trouble, not them. This extends to people not a member of this forum.
