I would appreciate any reputed member like suchmoon, LoyceV to come forward and help me removing the tag.
You have 6 "untrusted" negative feedbacks, I have 9. Obviously, I don't have any power to convince people to remove tags.
I want anyone of them to PM ChiNgadOr
That's probably against the rules:
29. Sending unsolicited PMs, including but not limited to advertising and flood, is not allowed.
Especially since he knows already:
I have tried to reach him through bitcointalk pm and telegram but got no response at all.
What can I do to get out of this tag?
Nothing. So just stop worrying about it. People have much worse feedback than this.
