Hi,
First, when you say
Account, do you mean [Battle Net] 'Account' or 'License'?
This is my setup:
- Account 1 (BN1) Max Licenses (BN1.1 ~ 8)
- Account 2 (BN2) - 2 Licenses (BN2.1 ~ 2)
- Max, I ran 3 bots (but mostly only 1 or 2 bots) concurrently
My experience (2 years botting, approx 4-5 million gold earned):
In the past, I have been suspended (bot active) on BN1.3 (GatherBuddy2) whilst live botting on BN1.1 and BN1.x and both BN1.1 and BN1.x never received a suspension at the time. I was literally amazed that my main (BN1.1) was still alive, and further BN1.x weren't 'checked' by the GM/Blizz rep at the time. Crazy, but it did make me believe that when Action occurs, it is the License that is investigated. This was a while ago however. About 12 months later, BN1.1 was gathering
heavy through 2014-2015 and I didn't care. That's when I received a 72hr Suspension. By now, my account had received 2 suspensions (2 Licenses, 1 suspension each -both 72 hrs). A year later, BN1.1 is caught in the March '15 suspension wave for 6 months and then again in December '15 -the latter being an
18 month suspension. Again, my BN1 was totally safe and all Licenses still available.
I no longer bot, and do not advocate it for personal gain.
TLDR -
If you're doing it on a smaller scale (personal use, 1 License at a time) you should be able to consider that your actions will jeapardise only your botted License rather than your Account. Unless you're botting 'many'
Licenses concurrently, we can expect 'License'
suspensions rather banning
Account bans. A lot of people have reported losing xx Licenses, but in those cases I'm sure we'll agree that they were botting for profit and
Account losses are a loss leader -part of the business model.
Just my experience, hope it helps and best of luck but keep your Main safe my friend!

PS,
Blizzard have openly iterated on their stance against botting, advocating suspensions rather than bans; it's an incentive (an engagement?) to encourage offenders back into the 'game' rather than to return to the 'botting the game'.

EDIT: if you want to trade Gold then use a Guild Bank -create your own Guild Bank(s) and use it as a way to pool your Gold; in the event of a Suspension your Guild Bank gold will not be conviscated but all Gold in your personal possession will be toast! So, use Guild Bank(s) for both safe storage and trading gold between alts.
