"Just" don't engage with them. A more technical solution is to make a custom feed that filters out what you don't like.
I have a script that generates an html file, sorting posts to tiers based on domain or keywords. Just as an example the shitty tier posts are now: bbc, wsj, vox, arstechnica; the top tier: itch.io, twitter, arxiv, github. Any posts from rare domains get into top tier, posts from frequent domains to middle tier. So it's mostly sorted to my preferences.
