The problem that i seeing is the unpredictability of ban. Because when running a lot of accounts you need at least a false "security" to do things, example: I will start botting 30 accounts at 6:00 and stop at 16:00 because 10h is, as debuffed said, "as much as you can go". But when you run 30 accounts and some is getting banned with 2h, others 5h, 17h, 28h, 1h, all accounts doing exatctly the same thing and getting different ban times
... it's a total mess.
