Haven't been around here for very long but when members are blocked in forums then it's usually because they have violated one or more forum rules. Sometimes that can happen surprisingly quick or even by accident so I wouldn't judge it. I think the most common red flags in general are rude behavior and spamming. If an ex-member still sees value in participating they typically rejoin under a different name so who knows, he might be still around.Why Vince Carter was blocked? - He seemed to have been very active for many years
