Hey
I bot on 10 accounts every day.
And like 19h per account (all at the same time) every day.
How to be safe ?
You should turn your status "offline" in game, left your clan chat and fc.
Don't do the same thing, if you bot like .. Cooking, take 5 minutes every 3-10 hours for activating aura or something like that.
After boting, do something different (ex : if you finish boting Cooking, do something different, like another skill).
A normal person doesn't log in all day at the same hour, and log off at the same hour. If you bot every day 10h, start the Monday at 10am, and the Tuesday start at 11am.
Some bot had a high bann rates. Be carrefull
