I see a few bots each world in  the taverly. Are they a high ban rate?

If you run it like an idiot and do deathwalking then yes very easily banned

From my experience, yes.

Anything has a chance of high ban rate. Depends on how you bot it (breaks, how many hours), if you have been banned before.

 

 

Usually, easy to get to spots are higher ban rate. So to answer your question, if you bot dumb this would be a high ban rate.

I ran one account at chaos druids for a couple of months, about 8 hours every night in increments of ~180 minutes with ~45 minute breaks. I stopped botting druids and moved on to something else, but I've yet to be banned. It does help that it's a very old (way over 6 years) main.
