I remember that in Diablo2 you could be banned when botting if you made new games too fast. So almost all bots had a randomizer between 1-20 secounds until you made a new game. Maybe its because you pretty much make a new game before you fully exited your old. I dont know just a thought.
I do think its normal statistical analys though. You dont need alot of data to see what kind of behaviour the owner to the account have.
I believe it is making games too fast, selling too fast, etc. I did see a sticky link on D3 main forums saying something regarding the number of games made w/i a certain period of time were being made
Game Limits Re-Enabled - Forums - Diablo III here's the copy/paste for those who are too lazy to check.

In the near future, we'll be re-enabling the limit on how many games a player can create within a certain amount of time. We've further tuned and tested the conditions that trigger this limit to ensure, as much as possible, that it only affects those abusing the Diablo III game service in a way that violates the Terms of Use ? for example, by using bots that create games in rapid succession.
The use of bots not only impacts the stability of the game service, but it also has an impact on the player-driven economy. While we regularly take action against accounts for the use of unauthorized third-party programs and bots, this additional measure will help us further preserve and protect the integrity of the game and economy in between ban waves.
Once this change goes live, we're looking for your feedback to help ensure that the limit is working as intended. If you encounter the "Input limit reached" message and feel you should not have, please let us know how many games you were creating and why. This information will help us ensure the limit minimally impacts legitimate players while still protecting the game against bots.
We'll continue to tweak the game limit as necessary, as well as continue to go after the few cheaters and botters that are out there in other ways. Our goal is to help ensure that Diablo III continues to be a fun gaming environment for all of our players, and we're looking forward to hearing your feedback on this change once it goes live.
We will update this post and unlock the thread once game limits are re-enabled.
I'm guessing Boss already knows this and a few others perhaps as I have seen Boss has tweaked the bot a bit for randomization of creating games.
