Yea, now we will see people venting in many new ways, like making two or three extra throw away REGISTERED accounts so you can blast away and not get your main account removed.
Anyone got a list of places where they ask very few questions and give you a e-mail account quickly?
How about a list of open proxy servers? Don't want to come from the same IP as your main account now would we?
Blocking unregistered was silly and solved nothing.
