I have found that most all sites band anyone anytime. The reason for this is simple. If sites allow there posters to bash each other they also have to allow posters to bash their sponsors, handicappers,etc and are susceptible to other outside companies trying to advertise on their site for free. It's a business decision not a freedom of speech decision.
I can understand and respect that. Let's just call it what it is. All in all, Pregame is great and an asset to the betting community. Case fuckin closed.
