Provide a list of blocked websites?

[Blockinlick]

I'm studying some pretty controversial subjects. Something in line to conspiracy theory, but nothing really extreme. I'm studying just out of curiosity.

There are some subjects that I'm aware I can't look into much on the standard WWW because they've been blocked for whatever theoretical reason.

I have Tor ready to use to browse sites, but even with Tor I can't manage to dig up any leads because the search engine still operates on Google-standard search filtering [Which wont display blocked sites in its results].

So I need some sort of list of blocked websites. Does anyone know of a site that lists a large catalog of blocked websites?
