In starting this thread, I didn't mean to ignite yet another dps-parsers-are-evil-no-they-aren't discussion, though I guess in retrospect it was inevitable.

That old argument is legitimate, but in a sense irrelevant. The fact is that SE has its feet in cement on the matter, and anyone using the main DPS meter out there and its add-on features like Radar are doing so at their own risk, with bans now underway (though here I agree with the person who said Radar was likely the precipitating development for SE's more active stance).

Fight Club rules aside, it seems to me that this situation will only change when or if SE ever provides its own in-house, non-third-party tools.
