I also agree to a certain extent that warnings are somewhat pointless, but on the other hand I think it could help in avoiding any similar rifts in the community in future. Usually when a person breaks a rule (any rule) they are giving a warning (in some cases more than one) before any action takes place. This depends on the severity of the rule of course, but I think in the case of community GA's a courtesy PM to inform someone they are in danger of being removed could be a good thing. Since it is really easy to achive the criteria needed to remain active on the forum (and by extension in the group) it doens't really matter either way to be honest.
