This site will never block any sites nor users for sharing different ideas of history, people, politics, environmentalism, economics, and/or culture. Bias and conflict of opinion would be detrimental to the trust and usefulness of this blocklist. You may have noticed a tutorial "How to Censor ZeroNet." That was a prank intended for pro-censorship newbies to block themselves.
