OP, I guess, Jollygood will withdraw the negative tag if you sign a message on this address.
It can be a start, but I would not be surprised if JG will
also ask 1xbit to prove the originating addresses are theirs.
Or is there already a platform or anybody who can certify that those are their addresses?
However, at least OP can indeed do his part, it's not that difficult.
btw. why did you wait this long to start this discussion?
Good point.
