That’s pretty interesting. It looks like they define inaccessible links as urls that get a 404 or the server doesn’t resolve.

I wonder if there are any real implications of this. We seem to know it and work around it in some cases, e.g. StackOverflow saying answers need to contain quotes from pages they reference.

needing a login that would require an email address is sketchy as hell on the surface, and there’s no explanation given.

The link to the explanation is right beside the text saying you need an account.
