Subparagraph (c)1(B) says that the only safe harbor for removing content is (c)(2). (c)(2)(A) restricts the criteria that can be used to remove content to the following: "obscene, lewd, lascivious, filthy, excessively violent, promoting terrorism or violent extremism, harassing, promoting self-harm, or unlawful".

The current Hacker News Guidelines contain stuff like "Be kind. Don't be snarky". These are broader than the text in (c)(2)(A). Therefore the safe harbor may not apply.

Worse, section (c)(1)(C) implies that removing ANY content by a user could make the forum liable for ALL OTHER content posted by that user, unless there is "good faith", but "good faith" is defined in section (g)(5)(A) to require all moderation criteria to be defined with "particularity". "Be kind. Don't be snarky" could be construed to lack "particularity".

The only alternative provided by this law would be to only remove content according to extremely legalistic moderation criteria. In my personal experience, all high-quality open forums require moderation with a degree of subjectivity with open-ended criteria similar to our Hacker News Guidelines. Given the legal risks of having to go to trial to argue about whether you are a "publisher" of other people's forum comments, it would be foolish for anyone to continue to employ open-ended moderation under this law.
