So I was successful getting about 25k honor before my first 3hr ban using automouse clicker to stay afk.
A few reasons why I think I was banned:
1) not moving out of the tunnel
2) botting for more than 3hrs at a time
3) botting while asleep and afk (8-10hrs sometimes)
I received the 3hr ban at my e-mail address around 5:30am today. I didn't even realize I had been banned.
So if you're going to do it - work real hard to find a way out of that cave. Otherwise you won't be able to go afk with peace of mind.
Warden didn't catch me - I was reported.
