@mk@bsd.network I agree with your points. But this would be similar to something like Better Business Bureau in the US. I believe it's an independent company that just has traction. While not all businesses are a part of it, they have become a go to for reports.
Something like this would at first just be email. This can be automated. Create an account every like 6 months. If that email address shows up on a mailing list, you know it's been sold and because it's an identifiable email address to the website, we know who sold it.
Because the badges would be handled by something like BadgeFed, we could remove their badge.
I agree though, an actual governmental body doing this, would be ideal and I'd be totally fine using this as an example. Nothing I'm advocating for I plan on being the sole owner of it forever. Even my show. I do it to see if it can work, to learn, and hopefully someday, hand off to someone to do better.
