It makes me laugh the way people set up a thread which is clearly intended as bait but then attempt to limit what other people may say in response. The modes naturally become part of the discussion when people start bleating on about 'griefing'.
As for the developers sanctimonious comments, it reads more like 'We are terrible gamers, for anyone like us here are some buttons to press to make those big nasty people go away'.. We used to be just good gamers, now in some Orwellian way we are refered to as gweefers.
Since we are on the topic of blocking people I'd like to propose that we are able to block all members of certain private groups. Its nothing personal, I'd just rather not play the game with a bunch of cry babies.
You can do whatever you like with your block function, I fully support your right to decide what you want to do with your game.
As to the thread rules you should take that up with the mods if you want.
