In short it was Vod who left the feedback.
OP wanted to pay people for a job, used his alt account to make it look like it took the job and was paid, to make the thread look legit.
When asked to prove the payment, OP refused, because there was no payment.
OP got red trust, tried to retaliate with the same, but his comment is obviously visible as untrusted.
Also tried to give himself positive feedback to zero the negative trust he got from Vod, but that didn't work either, so the last thing to do was complain in Meta.
