Detection theory.

[Alekssis]

I do not doubt the professionalism of the developers Demonbuddy. But experience shows that sometimes the solution may lie on the surface. Why invent sophisticated software to detect processes and windows open on your computer?
All the players know that if they call during the game chat, control your character stops and introduces characters from the keyboard. It is easy to write a program that will include an invisible in-game chat literally milliseconds, and analyze the data entered. At least I would have done so. I hope the developers will think about it.

But your theory is flawed, if they could detect demonbuddy or any other bot, why are many botters including me going strong for ages?

also if blizzard could detect the bots, why are they taking boss land to court? simply short and sweet... they know they can't detect us so court is the only option.

Not to be pesimistic here, but what you understand by ages seems to be different than what I do. In fact, nobody I know, and I happen to know maybe 30+ botters with well over 100 accounts, survived the ban day of december. That makes your ages smaller than my months.
Answering your question, my personal thought about it is simply size. They dont really care about 1-2 botters. They are worried about people who run far more than that amount. For all we know , tomorrow they could ban every Db single bot user in a new banwave like the dec one, but they know a small time botter wont run to the store to buy more copies, but a farmer probably will.

wrong, i botted for 2 weeks before, only hit paragon 50, only copy of d3 and was collectors edition lol, i shoulda bought seperate d3 but didnt think id get banned on december one, owell, they ban randomly everyone so get used to it

Detecting in big ban waves is fairly simple, where steady detecting is a lot harder.

Take last ban wave, the buddy team updated the use of way-points to open the menu before teleporting. First of all i am not a 100% sure this was needed but considering the products they created i am fairly sure this was for a reason.

Blizzard may very well have patched a network check into our client to detect if we use the waypoint menu to teleport, something they didn't check before. Take the knowledge of a two weeks period and you have 95% of the botters, probably more of the active botters. With this information you've got yourself steady information to release a banwave.

A couple of days after however, the buddy team updated our software: we now use the menu. Their method is hereby useless for a second ban wave and in no way a steady detecting method.

This is not just one check they could create, but they use them one by one to clear the air once in a while when they feel we are getting to big. Scare the kids of, let the crowd know they are serious about it.

Other than this there is of course scheduled hand checks which would show we aren't as human played as we say we are and old tripwires people still fall over (for example the creation of insane amounts of games an hour, which was never officially announced as a tripwire but hey: what is)

But anyway this is just my point of view on things, it is and will only be: speculation
