This is just a warning for websites that are still not using SSL.
Here is the uncropped image of the domain I blocked, but the non-SSL link still shows in my feed.

Try blocking in times.com and I bet you’ll get the same result. All results will disappear except this one.
It has nothing to do with the SSL.
You have to block the subdomains ( www.)
Could domain blocking automatically block the www subdomain?
Yes but when a link doesn’t use ssl the domain blocking doesn’t seem to work on it.
