Another great way to get banned

How do hackers avoid getting autobanned? Is there any way legit players could similarly bypass the autoban?

I have a theory that the reason hack-bots constantly change channel or go in and out of portals has to do with autoban avoidance.

The last time I was banned a few days ago, it was for the 'illegal program' reason, and I had nothing running except the game, firefox and a text editor that use to load passwords. I was training in a mini-dungeon, so I can't blame hackers passing through my map/channel for that one.

I've also got banned one time while afk on a safe platform, ie doing absolutely nothing.

So far, all have been 1-day bans, but I'm getting worried that the theory that if you get x bans within y period they become month or permabans could be valid. Anybody know if that is true?
Edit: Though Hellenzsin post makes that look doubtful.
