I think this always should have been opt-in. Don't parses violate the TOS to begin with in general? Why are all our characters funneled into such websites?

Now, behind the scenes, as someone who was an officer in a very high-end raid guild in the past, I can understand the use of such tools. It saves a lot of time having some info about applicants. A bad addition to a raid team can be disruptive and it can also cause a lot of drama trying to eventually remove them. Showing your credentials to be part of an exclusive team, IMO, is fine. If I wanted to raid I'd open my logs back up for any applications.

But for most of us with no interest in raids, recent events showed us that this info is just used to harass others in scenerios where the data is not even relevant.
