Do you think any of the VIP benefits come at the expense of the privacy of other members?

Not really. I can see who visits my profile, unless they have VIP and are choosing to to remain unseen. But my profile is there to be viewed. And I can now see who downvotes my posts, but they have to choose to do that.

Potentially true, yes. Unless the same features are available to everyone.

It wouldn't surprise me. I don't trust that any more than I trust anything else Tory.

Being VIP means you get to see who has been obsessing about you.
In a word, yeah.
