I just started botting the 90-100 quests this week (after doing 4 100s manually ughhhh). I must say it's really, really good but you do need to be careful. There's a quest in Frostfire or Gorgrond, (I forget which) that require the bot to click on a wooden gate. So far each one of my toons that has gotten to that point just runs back and forth at the spot. I had a missed whisper on one and couldn't read what it said so I may have been reported. I just make sure I don't let it run overnight anymore if I'm not past that quest. Unfortunately I don't remember which quest it is though. It's in a cave with ogres that requires you to click on the wooden gate.
Also if you have any repair mount, I've had an issue with it trying to mount up and repair / sell only to dismount and re-mount over and over. I have to manually repair and sell every couple hours to avoid it. I read a bit of people having that same issue on here. I even bought the Yak mount since it was thought to be an issue with the mammoth mount. It did not fix it. If you don't have a repair mount at all, I don't think it's an issue.
