I use this post frequently to post comments on SO questions that don't meet the quality guidelines for the site. I find it helps me to do my part in helping the moderators keeping the site clean. It is a valuable tool for me.
I've added it to my favorites so that I can easily link back to it.
Today when I was making such a comment (on this question) I found that the post no longer appears in my search.
I suspect it's been deleted, which I can't tell because my rep on MSO is too low.
What's happened to this post?
