Bot farming mounts and ban question

Hi,

I am thinking about botting for rare mounts on a separate wow account (wow2) but under a single battlenet account. I plan for the account to have no other interactions with the main account, given i have no experience botting just wanted to know the experiences of others on this forum re safety ie. if wow2 gets banned for whatever reason will wow1 be affected given they do not interact with each other in away eg trade gold and what not.

Would it be safer to bot on a separate bnet and merge them later?

Thank you all in advance!!
