Hi [u Stani™]
A couple of times lately in which comments to photos were not published, alltough the recipients (authors of the photo) did get mail notification of the comments. Happened to me both ways.
Latest is a comment by Renaiolo to photo http://www.hikr.org/gallery/photo1847395.html?post_id=98483#1
which reached me by mail but does not appear on the site. I commented on a few photos of other people lately, but never saw my comments appear. This happens irregularly, I think.
Hidden feature I don't know about? Others noticed the same thing?
