Do not be fooled by the " I bot since beta" answers. They are very hard to take seriously, or uncredibly lucky.
There have been two big banwaves in the past. First in feb. 2012, this killed 100% of all the accounts owned by the people I personally know.
Some people claimed to have survived; they could have been botting 1 hour every two weeks and still consider it botting, though. The relation of banned-not banned accounts here was 9-1 at least. Just go to the ban Section and it anywhere from page 30 to 60, you'll see the same date,
Second was after S1. It took most people that botted in seasons, but did only affect a reduced amount of people that did not season-bot.
Point being, the frequency of the bans may seem rare enough to give it a try, but noticing how you really care about your account, it is a clear NO.
