If you mean because of the script behavior, then yes I agree. 99% of the bans are not due to that when on tut.
Using crappy proxies yes. Was even a few subnet waves back in May/June during that prime season. Just logging into the account on that proxy for a few seconds was enough for some people to get banned during the wave.
I bot tut with Stealth just fine. Yeah I may jump through a few extra odd ball hoops to do it, but I do. Stealth could be done a lot better, hoping they look into improving it again after the AI transition.
Yeah no idea what you mean here, never seen a difference purely a difference from tut when running 3k through in a day vs like 15. Maybe if you don't have enough proxies and create too many accounts on the proxy too fast you can cause a mass ban wave across that IP. But you need to create like 350+ in a day.
