Does anyone know what happens with all the Gold on my Guild Bank if my botting account gets banned? Will Blizz remove it?
Assuming you have other toons that are also guild members with withdraw privileges... It really depends. Some people get everything (or mostly everything) wiped while other people wont have anything touched.. I think it is dependent on GM and how excessive you were botting. If you were power botting and then deposited 400k gold in the guild bank in one day then got banned the day after = good chance that 400k will be removed.
I've never actually seen any proof of them taking items or Gold from a guild bank. Its always someone who knew someone kinda thing... now accounts bening closed on the other hand...
