I normally ignore my spam file since I really don't care to read spammer comments, except to push the delete button. But I happened to look at it this morning and was shocked to find quite a few real people comments tucked away among the weirdo ads for real estate and make up and other things I'm too embarrassed to mention.
I went through and clicked the real ones as "not spam," but some of them are months old and anyone checking back to see why their post never showed up has probably long given up! What a very strange thing.
Have you checked your spam file lately? Found any harmless friendly comments from fellow bloggers hiding there unpublished?
