How would an optional, official parser be toxic?

[Ursa_Vonfiebryd]

It wouldn't so long as the parse data couldn't be shared, accessed or view by anyone else but the player who generated it. Because that's the only way you're going to get away with the 'general betterment' argument. If only the original player can see it then fine. Parse away.

Oh. And you can only see your numbers. No one else's.
