This is a question for the Less Wrong moderation team.
Suppose that I post a comment on a post, and the author of that post deletes that comment. Now, that comment isn’t lost, per se (as its contents are sent to me via private message), but it’s no longer publicly accessible. This is likely to be unfortunate, from my perspective, as I sometimes write comments with the intention of having something I can then link to (and often the comment-thread context is relevant to the comment’s meaning).
Would it be permissible to make a post (of the “personal” type) where I re-post any of my comments that are deleted in this fashion? (I am assuming here that the reason for the comment’s deletion wasn’t anything like “having this comment on the site is illegal”, “this comment reveals privileged information”, etc. Likewise, I am assuming that any such comment does not violate any general site rules—despite that it may violate the commenting/moderation guidelines specified by a given post author—and so its presence on the site is not inherently problematic.)
I do not necessarily disagree with you, but I’d like to request that discussions of whether it’s acceptable to delete comments, or to allow post authors to delete comments, etc., to be kept out of this discussion. My purpose here is just to establish whether this specific thing I am asking about is acceptable or not—I am taking site policy for granted right now.
