I think the real issue that everyone seems to glossing over is
>How can I make sure I'm not vanned for running any website
That should be what this exercise is about.
Regardless of if anyone posts pizza or not, similar to infinity chan if someone posts their manifesto or anything that might trigger any of the other infinity reasons why a government would try to get you shut down. If you even talk about sending the wrong coin to others your website could get shut down and you'll become dred pirate Roberts 2.0
Anything that has to do with any form of freedom will eventually have some government try to take you down, even if you're the gayest faggiest moralists like Kiwifarms.
Solve that issue first before you worry about what other people are uploading
