@dansup "unless breaking the law" is not a good idea, since there is no unique "law" but a whole zoo of jurisdictions, including laws made by dictators and authoritarian regimes that I would not want to see in control of what I get to see.

I suggest that rules for exclusions be published, so you know what to expect from a curated site. Also, document under which jurisdiction *you* are under.

Apart from that, the person maintaining the site gets to decide. If you disagree, set up your own site.
