This is rubbish. That blocked person also can't send you friend invitations, country club invitations and game invites and of course cannot abuse you by invading your wall. Main reason is, that you won't ever stumble over those morons again when creating multiplayer matches or when you want to join one. If you've found e.g. a sandbagger, block him, done. If everybody blocked him, he would only be able to play with himself but with nobody else evermore. That's the point of blocking and NOT useless at all but utterly necessary to not have to deal with each and every idiot on WGT. Got it?
