My situation is a bit more complicated, I have leveled around 8-10 characters using kicks' profiles on my main account. Hell, I leveled a char called Lvldbybot and a char called Leveledbybot using his profiles from 1 to 80/85. Recently I've started a monk, he's 63 now, botting about 8-10 hours a day, I think I've started 3 or maybe 4 days ago.
However! I have bought a new MoP license during the winter holidays when they had some discounts and such, I managed to get a fresh char on a fresh account to about level 10 or so then it got banned, managed to appeal and unban it tho (yay! lucky me).
I have bought 10 SOR accounts in the past 2 months, all for the US realms. First I bought 2, botted on them for about 10 days of /played, no ban (might I add that I've been botting on them for the past 2 months about 5-10 hours a day). And I also bought a normal Battlechest which I have added to my account for AH bot purposes (Not banned either, managed to make about 250k+ selling Outland herbs/ores and Northrend Herbs/ores).
All good and well, then I bought 5 more SOR accounts, I think my mistake was that I have activated them all 5 at the same time and started leveling them via Dungeon buddy, ran 2 healers, a tank, 2 dps . They got banned within 2 hours for "Abusing the Economy". One week later I bought another Sor, waited 3 days, bought another one. So I had 2 old SoR accounts and 2 new ones, the 2 new ones got banned as soon as they dinged 85, 525 herb/mining . Actually they got banned a few hours after I clicked on the MoP 10 day trial.
Bout a month passed, I've looked into some "solutions" I thought they would ban me because I'm from Europe and was botting on the US (thought they would check my ip or something, w/e I'm stupid), so I bought a V.P.N., changed my IP to California and bought a new account. I logged on, noticed that I had HUGE lag, normally I would have about 180 ping, with the V.P.N. on I had 800+. The bot ran Kick's Hyjal profile, I think he finished the first 3-4 quests and then it got banned, like in less than 25 minutes since I bought it .
I'm not sure if they check for botting more rigurously on the US realms than on the EU, all I can say is that on the EU realms I've managed to bot about 10 chars to 85 or 90 (5 of my lvl 90 chars were botted from either 85 or 1) and on US, they either got banned within 2hours or after 1 week.
I wouldn't blame Kick's profiles for the bans tho. That's my input on the subject .
TL;DR: Have a potato.
