Just wondering, would like to know. Also for 12+ hours a day simultaneously - not necessarily the same script, though. 

It all depends on scripts, methods and such. 

If you do that then as soon as one account is account botting, it would not be difficult to catch the rest of your accounts.

This would lead to them all getting banned and you wasting your time.

 

12+ is a lot of time for a bot to be running so that would increase your chances of getting caught.

 

I don't think scripts would really matter in this since as soon as one account gets caught, the others have high chance of getting caught as well.

I had one botting fishing and one botting hunter, both got perm banned.

If you bot with caution and don't suicide an account you'll most likely be fine, the only issue is that if one account gets banned, your other account is screwed, they MAY (very low chance) let you off with a 2 day ban but most of the time its a permanent ban as well as your IP getting flagged.

I've been botting accounts 2 at a time on the same IP address and changing the locations of the IP's between each time i swap to the next set of accounts.

I havn't been banned yet and I bot ~8hrs a day on each. Mostly at blast furnace but also power mining and agility has been done.

I wouldn't reccomend botting for 12hours daily, it will only cause you a Perm ban. Try 8hrs a day and take breaks.

I ran 2 bots approx 10 hours / day without problems , when i started with third one i got caught after week, the one got banned was making money for me , others trained combat.

Penalty is death.
