Just to add to that, uBlacklist has a power feature called subscriptions. Which is massively under utilised.

It enables a collaborative effort in blocking spam / low value domains.

If you make a block list, please submit it to the list I’ve made: https://github.com/rjaus/awesome-ublacklist

(There’s no great subscription discovery as yet)

Oh man, this plugin is going to save me hours of time over the next 30 years. Goodbye forever, cplusplus.com

I installed it and it's—ok? For search results where the spam overwhelms the signal (it used to be able to do a decent reverse phone lookup by putting a phone number into Google), you end up with empty pages or mostly empty pages in the search results. Better than nothing, but it really should be a feature from the search engine, not a browser plugin.
