Apparently, trol^H^H^H^Hpeople that post auto -1 are only allowed to post twice a day.
Now, this may seem good (No more crapflooding! Yay!), but I think this may do more harm than good.
I think we'll see a rise in the amount of troll accounts. This is pretty much a form of censoring. Trolls can't redeem their accounts (what if my first post ever gets me knocked down to auto -1? How can I get my respect back if I can't post??).
The worst problem, though, is that they'll just start posting as AC (score:0). Its a lot easier to deal with logged in trolls, make them your foes, and keep them at -1 than having to sort through them to see legit AC posts that add to the conversation. Why not allow the subculture to scour down at -1? Its easier to contain them there!
