I think that it takes Blizzard a lot of resources and a lot of time to do a banwave. In respect to mmoglider, they have to crack the current source code, then detail how it is getting around Warden and then work on a way to detect it. All of that takes valuable time and manpower. After they get this new anti-hack to work, I'm sure they test it in a controlled environment. The next step is too implement the new detection update and try to slip it through the cracks in either patch or a warden update. After this is all done they start to 'detect' players that hit there criteria then investigate them. If there test pool is overwhelmingly bots then they will get the list of accounts that have been detected then bam!..mass bann-age.
The mass bans happen in around 6 to 9 month increments, so if your going to bot; bot now!
Bot as much as you can and try to keep track of Blizzards banning cycles and you will have a better chance of avoiding the ban-hammer.
