This page is great at telling a list of popular websites we should simply block/remove from our search results (can use uBlock or uBlacklist). When you search for "Dotdash Meredith" or more specifically "is part of the Dotdash Meredith publishing family" you get a lot of widely known websites. I am removing all these via uBlacklist atm.

Are there any other similar family of websites which we can lookup and block?
