Yeah. If after some more consideration, Jake would be allowed to post again, he'd better do so under another name. I believe that despite the fact that most people here are acting very mature, Jake as Jake would still inspire a certain amount of hostility. Anyway, I'm voting for a card-like system. Not because I think (nor hope) it will be needed often, but because I believe that you should make sure people mean what they say (sarcasm and text) and that they should have at least one official warning.
Then again, such a system may be a bit to 'childish'. We should be able to work things out the regular way.

and plunged burning into the heart of a great wolf-chieftain.
All the others fled. -J.R.R. Tolkien, The Lord of the Rings
