@nooblet: If this was to end into a massive wave of abusive bans from the admins, the only thing that would happen is that people would wander off. There is nothing this "announcement" covers that isn't already covered by the infamous 0.0 rule.
This announcement appears to me as nothing else but a warning to some players that they will now be dealt with. Will it change anything for the common user? I sort of doubt that.
