it doesnt get unbanned, i heard of friends that got their balance back, they had to make new url
and admin sent them the money there, but this rarely ever happens, as he likes to scam users.
my url has no more value, so theres nothing to loose
I have used satoshimines in past many times and deposited some bigger amounts there but i never got scammed,some times deposit problem came but their admin solved my problem when i contacted him.
When you sent the mail to the satoshimines admin,he normally responds with 24 hours or 48 hours max.
