If this really lets me block certain websites for good, then I'm sold.

I absolutely hate those sites that scrape other well-known sites (like StackOverflow, Quora, Reddit) and add ads and SEO spam. They are increasingly better at being on the top of the search results, and I cannot get rid of them.

I'm in the same boat. Right now I do this rather manually, e.g. uBlacklist on chrome.
