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?
Fair enough on the "rampage" comment if it's to do with megathreads - I admit I only scanned. I can edit or remove the comment if you wish. I'm not here to score cheap points.
I like that you are being so open-minded on this - regardless of whatever you infer from my posts, I want you to know I respect this.
Your idea of bulk PMing is excellent. May I suggest that the PM list be shared with the mods also? That way they can filter the ones you have to tag by banning as many as possible before they get loose - if they don't improve, of course. 2 weeks seems more than reasonable - very fair.
Great reply. Thank you

Now actmyname starting to realize that the decision he made to tagged bunch of accounts was not fair as he considered shifting the from negative to neutral trust which he made some guidelines himself that if not followed based on his evaluation,he will again red tagged certain accounts.
Why not just focus on what Theymos said "
Do not rate people based on the quality of their posts." because his words are final, don't make your own judgement which would eventually lead you in making a decision which is against the rules.
The best solution to do IMO is just to put a rating in neutral trust as that is fair, we want to be fair here, as this forum is for everyone who wants to learn.
