I personally started my botting career at Powerbot in 2009, and after about half a year, I found Robotz in Disguise through an ad on their site. Those short months I was with Powerbot I had 3 bans. I switched to RiD in April of 2010, and since then have botted over 3100 hours with their 12 bots, earned 13 99's (12 on my main and 1 on my def pure), earning over 200 million experience, while botting 6-20 hours a day. RiD is the only botting site I've used that I've never had a macro ban from.
I've been reported over 40 times that I've witnessed, even by Player mods, and I still have gone over 2 years untouched.
Basically, I feel safe enough to go all the way to 2496 total level breaking guidelines without worrying about being touched by a macro ban.
