Truth is... botters are a beneficial parasite... if kept at healthy levels.
You might say "I bot smart and didn't get banned"... truth is.. you simply were not "culled" with those that were banned. Just like there are a certain number of "beta keys" assigned to accounts... there are certain number of bans assigned to flagged bot accounts.
Doing this keep gold flowing and people playing.... it also keeps just enough guessing to have botters buy another round of $60 a whack clients in bulk.
If you are a casual botter... it doesn;t matter what you do.. you will either be selected or not for ban. If you are a profit-focuses botter... bot 24/7 roll over your gold quickly and replace your accounts as they get banned. At $2 a mill.. it only take a few days for a bot to pay for itself.. then it's pure profit.
