Too bad for them, they got banned. lol
The restriction anyways looks like burner bnets used to bot can’t just store ill-gotten gains inside bnet funds immediately on said burner. They’d have to have a “main” account gift them new xpac purchase every time they’re banned, so gold would need to be funneled to the real bnet for the first month of each burner account’s lifetime.
Existing automated dirty gold trade account closure mechanisms would probably flag that last part easily.
