IconFirm made assumption that account johhnyUA changed hands and they probably didn't give a fuck to check whether account is sold or not just because of
yobit's signature, which is the main reason of feedback anyway. JG's reference points "kvanko-johhnyUA alt accusation" topic, as there is no way to prove or disapprove it, JG probably see him as cheater who will do anything for money and he decided that yUA is dangerous, then he left him feedback and send him to "Ignoreland", which is, btw, according to yohhnyUA OK to do:
Ignore is fine, red trust to tell everyone that JG is ignoring someone - not so much. Same with the ratings that say one thing and point to another... it shouldn't be a puzzle, it should be factual and indicate "high risk in trading".
