I think we need a general review of this situation. I read the new page a lot (and flag a lot) and I am consistently seeing worthy submissions from people who are hellbanned. I don't have the time or inclination to dig into comment histories to figure out why that took place, but it seems to me that it ought to time out after a week or somesuch except in the most egregious cases.

Although I can upvote, there's no way to bring a worthy [dead] comment back to life. It's rather pointless to punish bad behavior (by flagging) if there is no corresponding method to reward good behavior.
