Actmyname....well, this one is tricky. He's engaged in discussion on this topic, which shows an open mind. But then there are those....rampages...which are also opinion based.
Which rampages? Are you talking about the bulk ratings in which I go to a spam megathread and tag prominent users there?
I have already stated that the negative trust will be removed when a week's worth of quality posting occurs.
There is one option that I have which could work: to instill a neutral trust feedback that prompts users to improve their post quality (and to PM them in bulk about it the day of). If they do not improve the quality within 2 weeks a negative tag will be placed upon them. How do you feel about that?
