As this was cross-posted from users, and might also be better followup to The beta.rust-lang.org PR debacle, I’ll offer one point of user perspective here, which I hope you will consider in the new year:
The moderation measures applied during this and other incidents, like locking of topics and lots of hidden (flagged) comments, appear in most cases cases to go beyond any tangible enforcement of the code-of-conduct. The practice extends to github issues as well.
At the very least, these moderation measures have the optics, to outsiders and new-ish users, of censoring dissent and insincere openness.
Personally I think this heavy handed moderation is more worrisome for the future of Rust than any shortcomings of the new website.
