Parsing unfair but okay?

[Rolder50]

Unfortunately, this is impossible in this game—since it gives no indication of personal skill or personal damage dealt outside of sitting down with an Excel spreadsheet, a calculator, and a vast amount of time on one’s hands. If you ever wish to know your true performance, that is only possible with a parser. You are mistaken if you believe anything else in this game will inform you of whether or not you’re doing an adequate, below adequate, or above adequate job.

If SE were going to ban parser users, then they would. But they know that doing so kills their raid scene. So they allow it “unofficially”. You can wave around the ToS as much as you want, but it’s meaningless if it isn’t enforced.

Not to mention that actually implementing the ability to track whose parsing would likely take a ton of dev time, if it's even possible in the first place. I'd imagine the large majority of players would rather have that dev time spent on new content.
