So now when you comment on Gawker if someone replies to your comment you can choose to reject it.
Yeah, nobody on the Internet would abuse that feature at all.
That said, you can approve any reply at all.
It almost makes me want to make some super douchebag comment and then get tons of you to make douchebag replies and create the ultimate douchebag thread.
UPDATE: Someone has already gone with the idea of creating the most offensive comment possible, then approving other insane comments and building the most obviously fake flame war possible.
