No arguments about that particular site. You found, what you found.

But that is also what I keep saying to people, investigate each case and
be sure about it first. The pattern you created from this one site was
applied *everywhere* all at once. Nobody knows what its broken already,
or about to.

So best way is to create a pattern for the site and any others you find
using the same software. Maybe you could sniff the Server headers or
something to identify a common CMS system doing this and apply the
pattern to its outputs. Lots of captures but still less than _everywhere_.
