I just made a blog post about this here: https://www.inaturalist.org/blog/25983-hiding-comments-on-inaturalist
But basically, following up on this discussion, we’ve introduced a hiding comments functionality on observation pages, and it’s now live. So curators will now not be able to delete comments on observations, but they can hide them. iNat staff can unhide them or possibly delete them if necessary.
It would be good to get some feedback about this. I know having the ability to hide (and not delete) comments on flags was also requested, but let’s see how this goes first. Here’s an example you can check out: https://www.inaturalist.org/observations/26811289
