They check IP's sometimes, just don't xfer everything straight from your bot to your main. Have a mule account that goes between them. So just x'fer everything to a mule, or sell the gold from the bot if you might be worried. I've noticed Jagex just banning multiple accounts recently that may be involved in botting/RWT/hijacking
"Apparently" ess mining is risky due to "high ban rate," but I haven't heard of anyone getting banned for a long time. So I'd say you're safe. Even if you get banned, it most likely will not effect your other character. Out of xxxx+ people botting ess, what ratio actually gets their other characters banned? Slim to none.
