It may be that these were scammers reaching out claiming they could influence DT/flags - I have edited my initial message about it because I don’t have clarity on who it was/whether it was genuine.
Update will come tomorrow on the rest.
Definitely scammers... Similar to those crypto recovery chaps who reach out to victims claiming they can recover the money but have to pay up some upfront fees. DT feedback can't just be bought like that and in case of any manipulations, it would easily get noticed.
I know the system is not 100% perfect because manipulators appear once in a while, but they do get noticed.
About this case, some members may have acted because of a number of accusations that sprung up with no clear explanations from your side, but the feedback can be reversed after proper clarification.
Following this case closely.
