Stockfriend:
You should send a PM to George and the Agoracom Managers detailing your complaint along with the name of the HL who has that avatar. I checked the HL list on CUU and did not see it. Perhaps it has already been removed. I personally feel that HLs have a great responsibility to faithfully abide by the six rules as well as not letting personal opinions interfere with their judgment concerning such issues as banning and violations.
Regards and good luck with your CUU investment.
