I selfhost it on my laptop, pretty easy, and I always have it just the way I want it. Still pushing shit uphill with the AI crap, but better than any one search engine (it amalgamates many). Relevant to OP I have a large block list enabled, but it’s very much a moving target.

Been happy with FreshRSS for years now (TTRSS before that). One thing that really improves it is RSS-Bridge which turns a lot of non RSS sites into feeds (and a lot of truncated feeds into full ones). It’s also a list of what hackerly types will put effort into getting a feed from, so self-curating in its way. Enjoy…
