My account already has an infraction on it from botting Runecrafting.  I'm inquiring if I were to bot auto alch in my player owned house what are the chances of getting banned?

I got the botting infraction about a month ago

I personally wouldn't risk it if the account has a previous ban. If you plan on alching using a script I wouldn't do it for very long at a time.

If I was going to do it (never bot on an account you care about), I'd mouse record it ( 20min + loop) in poh.

WIth the rs base client ofc

If youve been banned once and you keep going after then there is very high chance they keep monitoring your account and the ban will come in few days or hours.

Your account is flagged. If you run it again, you're more than likely going to be flagged again. Either wait for the ban to expire or simply don't do it.
