Some of the early iterations of the ToS's some Grids put up for authorization, sounded like they collected and held on to all information about visitors for 7 years, not just IP.

Thanks for featuring a picture of my avatar and an alt. Also, thanks for mentioning my good friends Checkpoint Charlie and Patty Paranoia. However, you forgot to mention Alliteration Alice...

If I see that popup message I just go elsewhere. I simply can't be bothered to faff about. If I have to jump out of the viewer to gain access to a location then I'm not going there.
It reminds me of the constant requests to accept cookies which you have to jump through hoops to decline.

Sounds good in theory but too often those grids requiring GDPR authorization have problems with allowing the avatar in even after accepting the ToS. Kitely's to their credit works or at least did for me, but have seen a number of other commercial and non commercial grids where it did not to the point where when I am faced with the pop up, I don't bother and look for somewhere else to visit.
