My opinion is there is too much censorship everywhere we turn. If ALL the participants are actively involved, then that makes someone fair game and they have opened themselves up to scrutiny by their own posting. Turn about is fair play. Those that come on in an arrogant manner to blast others need no protection.
However, I believe that if someone was NOT a participant and they were being talked about, then maybe they need protection. If they have more than one account, it is an unfair advantage to have numerous accounts. The Terms of Service currently do not prohibit individuals from creating more than one account on MT. It should NOT be allowed. That in itself would diminish the attacks since I believe the ones doing the attacks have different accounts from which to do their attacks.
Lastly, if someone doesn't like the content, they should go to a thread that conforms to their personal standards.
