Removing yourself from an IG #56

In your description of Interest Groups, you say:

The consumer is able to see the IGs they have joined and remove themselves if they don't wish to be targeted in that way anymore.

I like this sentiment a lot! But how does it work in the Edge design, where an IG's bidding behavior can draw on information from many other IGs as well?

I'm comparing with the Chrome design, with single-site bidding behavior. If I don't like an ad I saw because of a bid from IG-1 which I was added to on site-1, then I can delete all the IGs I was added to on site-1. Yay!

In the Edge approach, I might see an ad which looks like it came from IG-1 added on site-1. But if I delete that IG, or all site-1 IGs, the very same ad might appear based on the very same underlying data, this time coming from IG-2 joined on site-2.

Maybe the only way for my copy of Edge to know that it's deleting the underlying targeting data would be to delete all IGs owned by the same ad tech? Or, since advertiser buy through multiple ad techs, maybe you'd just need to wipe all IGs on the device entirely?

This seems like a big difference between Chrome's single-IG and Edge's many-IG bidding model, so I'm very interested in hearing your thinking on this UX question.

The user can delete the right IG (because the user does not like the ad for any reason) thanks to the browser showing the the connexion between every IG and ads.

Question : As an IG can be created with an explicit name (e. g. _sitenameadvertiser) or with a non explicit name (e. g. random code), how to make sure the name will not confuse the user with a risk of deleting the wrong IG?

As an IG can be created with an explicit name (e. g. _sitenameadvertiser) or with a non explicit name (e. g. random code), how a user can understand and remove the right IG among others?
