Instead of blatant ban evasion, Riches is living with Lioness and seemingly vading through her account.

Lioness confirming that Riches was coming to live with her (right around the time of his ban as well.):

I have zero doubts they're different people but it also seems very, very likely that Riches is conducting business via Lioness' profile. Also worth noting Riches disputed and was told to pardon but has not done so since then, meaning he's likely still trading on Sythe and has no need to get his previous profile un-banned.
