There was another article here on HN some time ago on how big media publishers are littering the web with spam recommendations https://news.ycombinator.com/item?id=39433451 (https://housefresh.com/david-vs-digital-goliaths/)

This listed review spam from Dotdash Meredith which I used a clue to search and block all sites by them using uBlacklist.

Edit: Found another article saying the same thing there are only few big media giant's dominating search https://detailed.com/google-control/
