Thud has no bans that any single person knows of. Macros haven't been banned besides the macro+script type things done with screenshots and other program combos for basically botting but was super easy for them to catch.
The current main bot source doesn't inject into the game and manually uses your keyboard and mouse and just reads the game without injecting is the main issue with them catching this. It has almost 0 ban reports and most probably got banned doing other stuff / manual reports.
Demonbuddy back in the day could tell when Warden went active and was going to find it and shutdown until they could find it and hide it again. Tho demonbuddy injected to the game and got banned so often.
The stuff I said is just stuff learned when I used to do all that back in the day RMAH stuff with 20+ accounts and early season botting and quad box botting etc.
As for the rest im not certain I haven't touched the game much in a while since I moved to PoE in 3.0. Diablo just got monotonous paragon farm and even if you botted it did nothing without a group to also get to gr 150 for gems and augs. Forced grouping is garbage.
