currently it's not mentioned anywhere, but i don't where it would be best to add it anyway
https://kagifeedback.org/d/459-mark-paywall-articles
include what exactly is meant with paywall.
I assume "you can read one article a day free if you login" is still considered paywall
but is "you can read all our articles for free if you have an account"?
might be good to clarify in the docs
side question: is this based a public url list somewhere?
because then reporting new websites would just be a PR away
