I use vanilla accounts to trade to Pusada. The accounts do eventually get banned, but it's not Pusada fault per se. They're definiately legit, and I just consider the lost of vanilla accounts to be a small fee you have to expect to pay in this "business". Blizzard seems to be less likely to ban an account with an active 80 on it (perhaps any active toon) than a disposable vanilla account, but I personally prefer to replace vanillas instead of adding additional risk/attention to my farmers. I do multiple exchanges on different servers on a vanilla account, so the risk of being banned is expectantly high. There is still plently of room for profit, so currently it's not a big enough inconvenience for me to be overly concerned about.
