It's unfortunate, but there's not much that can be done about it. Reporting is pointless because it's difficult to verify that someone is playing a bot to the point that they would be comfortable perma-banning; and the person REALLY REALLY looking like a bot doesn't count.

The amount of time it would take to confirm, coupled with the fact that people would be reporting basically everyone who doesn't respond to a /whisper, makes the entire proposition futile.

The only solution with a reasonable shot at success would be to allow SE to install spyware on all of our clients, and monitor everything we have running while in the game.
