Question about risks on different accounts..

Hey, ive had hb for years, but only really botted in Cata and never got banned then.

Nowadays it looks like blizzard is more aggressive with bans.
I only bot on another account with different name etc but same pc as my main account
I NEVER bot on my main account, but i wonder if the bot account gets banned, can my main account get swept with it too? I'd be devastated, even had nightmares about it xD
Is it safe to bot sametime as i play my main account aswell?

Thanks in advance.

 

no one knows? :x or could enlighten me with some tips
