If you're being honest, they may have got you for Ashita. Not sure what tools they're using or if any of those plugins are detectable, or some idiot special task force guy saw you speaking about 3rd party tools and figured you were cheating. Proof they do ban for windower or whatever:

That's a SGM who said he's been one since April 2006, so, whatever they're using, they can detect, just not sure WHAT is flagging, cause if that was the case, a LOT more people would be banned. Also it's anything you did in the last 6 weeks, according to the GM.
They will never tell you what you were exactly banned for; just third party tools, don't waste your time asking. He explained if they told you, the developers would find work arounds and fixes so the bots couldn't be detected by their tools.
This wasn't for my account by the way, was calling one for a friend cause support center said to have a friend (me) call a GM in game for him cause they couldn't help.
