There could be an intermediary status between hoster and editor : a "displayer" would not be liable for what its users do. It would (unlike a hoster) be liable for the moderating choices that he decides to do.

There might be additional requirements to benefit from the hosting status : of size, power, economic model, &c.

(Some of this has now been implemented in the EU.)
