Then come some restrictions to the trolls: If their troll-score gets too high they are restricted from creating new threads. Higher still, and a possible temp-ban is in order. What do you guys think?
I support your suggestion, because troll is not allowed, but I still see some users continously troll over years, and it seems they have not yet get any kind of bans (as I know). Not sure what happened more than 2 years ago with trollers, but last 2 years, I have not seen trollers got ban (by their trolling, not from plagiarism or spam, eg.)
3. No trolling.
