Your username was deleted because I asked you if you had a vendor account (you were offering drug samples as well as wanting to sell a bitcoin miner) - you didn't answer. I told you it was your one and only warning to stop advertising without a vendor account, but you ignored my post and instead continued to offer samples. (from what I could tell, you did not have a vendor account) So, as is policy, when you ignored the one and only warning and continued to break the rule about not selling without a vendor account, your account was deleted on the forums.
