How interesting. Bing doesn't do this, which leads me to believe it's not a matter of legality. Is Google simply electing to self-censor results that it'd prefer it's used not to know about? Strange move, especially given the alternative Google does index is almost definitely more nefarious.
As many have pointed out, this just makes it easier for actually malicious sites to get traffic.

At the bottom of the page click on the DMCA complaint, you'll find all the URLs you shouldn't ever, never ever, click on~
I assume that, if they legally could, they wouldn't show you anything
More than once I've done a search for something pedestrian (no intent for piracy/etc) only to notice the "some results removed" link. Out of curiosity I've clicked it, just to see what crazy things have been removed, and been quite amused/interested in the results.
I don't think everyone is seeing this, because sometimes I see this but sometimes not, seems to depend on the query. Searching for "piratebay" doesn't show it in the bottom (I live in an European country [also in EU]) and meanwhile, official thepiratebay website is blocked on a ISP level here.
I'm curious if that's the case for you as well, or if it's my ISP blocking (I wouldn't expect to see the cloudflare error if my ISP was blocking but I don't know).
I bring this up because if the site is unresponsive from wherever you're searching (or perhaps unresponsive for all, idk) then maybe it got de-ranked on google.
P.S. Yes, it's their new official "readable" onion site link.
