If you're doing stuff for investigative purposes, use a burner account and not the account you want to keep
Agreed, but I don't think there are a hell of a lot of people doing "investigations" about account sales, nor do I believe this member was doing anything other than inquiring about buying an account. Everything after his initial post sounds like an excuse. It's too late to claim you were trying to do the forum a service at this point, and that claim isn't credible anyway.
