I have been botting on my main account since i got the bot. Never had any trouble.
Sometime when i get home from work or wake up, i just go AFK in POE(everybody go afk in a game at some point)
i think it is more dangerous to transfer orbs to your main from a dummy account. but that is personal.
if you bot on your main, try to keep your friend list small, with only people you REALLY trust, since only way i see of getting banned, is getting reported.
And by the way, i live in a house with my brother and he also play path of exile. We both have same IP. never had any trouble with that.
but i dont BOT 24/24 nor am i connected 24/24
Stay safe, and yes, you are way better botting then spending real $$ for orbs
