1) Trust ratings are almost never moderated.
2) He's not in default trust, thus his ratings are not visible by default nor effect you by default.
Conclusion: If he/she/it/they do not want to remove their rating, there's nothing that you can really do about it. I have a ton of false feedback on me from butthurt people that I've busted (not saying that Timelord's feedback is or isn't false though).
We have removed our feedback
This user makes absurd and baseless accusations with absolutely zero evidence that my account is linked in any way with any of the accounts he accuses me of being. I'll remove this when he can provide any evidence at all.
From Timelord profile, we are in no place to fight with any members here, just want them to respect each individual.
Anyways I will personally leave a PM again to Timelord on firm's behalf, hope he responds this time.
