I have removed their previous negative while I look into the current state of events (which are unrelated to why the negative was given). Do note that I was being threatened with a flag[1] unless I comply, not that this was the reason for complying.
[1] I don't see how someone has a "right to give a flag" if I don't comply with a rating review in time.
Publicized PM because cases are on-going and I don't want to keep this in my box.
Actually they are confusing flag with trust rating. By giving flag, they surely meant giving red trust if red trust for not paying campaign participants isn't removed.
