To take the best advantage of this, you want to crank up the results per page setting in the search engine. This is because the deletions simply cut results form each page without the results being repaginated.
I made a lot of use of uBlacklist; but then I found Huawei's petalsearch.com, where pretty much none of the crap that I deleted appears in the first place.
uBlacklist is really just a band-aid solution for a garbage search engine; it doesn't address the root cause.
But I just tried the search terms "tiananmen square massacre" in PetalSearch. It comes up with the Wikipedia page on the subject, just like Google does.
The second result in PetalSearch points to the rationalwiki, whose text begins "The Tiananmen Square Massacre was a ruthless crackdown on a pro-democracy protest ..."; and that is quoted in the search result.
The next results after that are news items about Chinese censorship:
"China censors tank-shaped Viennetta ice cream on anniversary of Tiananmen Square massacre"
"China Censors Top Livestreamer, Fans Question Potential Link To Tiananmen Square Massacre Reference"
and others.
Seems all right to me.
Of course, I'm not able to repeat this test from within China; but how would Google and others fare there?
