Even if I tell you yup totally safe..are you going to believe me?
You'll probably ask are you sure how do you know?
I might make up some grand convincing tale..
I might just say nothing is safe..nobody but Blizzard..sometimes not even them just their auto ban knows what it flags..
At the end of the day you're on your own..everybody is since no matter what..if a ban ever does come you're on your own..
You might get some suggestions on what to say if you ask persistently enough..but that's about it..
Here is what I do ....
All my legit (non botted) characters and my botted characters are in the same guild, along with friends. The bots deposit goods in the guild bank. The guildies use them.
When my farming accounts are banned, yes I've had quite a few, the goods in the guild bank are fine.
