Today, I posted a comment (comment #0) to a user's answer (I know which user,
but I'm not revealing it in case that should be private) in an attempt to bring that user's
attention to a specific pair of other comments that I had made (comments #1 and #2).
More recently, when I looked at where I had posted comment #0, it wasn't there any more.
I then checked my activity, and it didn't have any record of the comment
(which, I believe, is what happens when comments get deleted).
Would comment #0 in fact have been deleted due to just trying
to bring a user's attention to comments elsewhere on this site?
