the thing is that most vpn are designed for consumer use to bypass restrictions and all connect to the same server with same ip, which is obviously bad if a goldfarmer previously used it and got banned and ip flagged. Yours might be different, not to discredit your purchase. I would recommend socks5 private proxies used directly on osbot or via ssh tunneling
yeah i think darkminer is a often used script and mining has a high ban rate anyway.
Make sure to used a private vpn (i.e. only used by you), NOT a shared one. otherwise you'll get banned really fast
what script did you use?
bot in non-hotspots, use good but unsaturated scripts, and use socks5 proxy if you're multi botting, and make the accounts as unrelated to each other as possible
Follow these steps and your ban rates will be minimal
