I have 25 level 85's and one level 84 at the moment.
3 warriors, 2 rogues, 2 mages (soon to be 3), 2 warlocks, 3 priests, 2 shaman, 2 druids, 3 paladins, 2 hunters, 4 death knights.
No bans, only one suspension in almost 3 years. One of the hunters was my 25th 85.
Im a very careful botter limiting how long I bot. The guides on the forums for lessening your chances of being caught are pretty on the spot with how I have always botted. I highly recommend everyone read them. I am at my pc about 90% of the time when I bot and am quite social when running it.
I have had my ups and downs when it comes to my paladin, lock, priest for cc's but all in all I think I did well for getting all these toons to 85. When MoP comes out I will probably only level a few more alts. None of the toons I have I ever plan to sell, I only have the 2 accounts, but I play multiple servers and like to make sure I have all the professions covered.

I only raid on 7 of them at the moment on a steady basis.
PS for those wondering why so many toons, well I play multiple servers on a steady basis, I also play both factions. I have allot of time on my hands so why not have a plethora of alts.
