I got 99FM with it on my ironman, 8 hours a day and 90 minute sessions are WAY too long. You want to set the bot to 10-40 minutes (randomized) bot time and then a break between 15-30 minutes (randomized).
I did 3 hours spread out across the day. If you really want to avoid bans be sure to do some WT manually.
You might wonder why only 10 minutes at times? More often then not when I do manual session I only log in for one or two KC and log off.
Botting will always have a risk, especially on an IP you got banned on before (flagged). If you care about the accounts make it look as humanly as possible. And playing giga efficiently for over an hour+ is really sus.
