Ask HN: Is there a curated list of tabloids somewhere?

I am looking into ways to block all the tabloids in my home network, but I am having a hard time finding all the offenders for all countries, mainly in English, but other languages would be welcome. Wondering if somebody else has done it before, otherwise I will just build it myself.

For a bit of context: I have an elderly mother in law with a weak heart, and believe it or not, she truly gets agitated and upset when reading material from these sites, which in turn makes her physically ill.

I have told her not to go there, but from time to time her friends share an article that will give her another anxiety episode.

My own elderly mother also tends to get upset with these kind of news, but at least her heart is in working condition.
