I get a fair amount of spam comments. Seems my blog has been picked up as a regular target for ecommerce sites. Sadly, I have not been keeping up on my spam folder and was surprised to find people leaving great comments, but they were flagged as spam. Figured I was supposed to be getting notifications on comments being shuttled to that folder for moderation.
My apologies to folks that have left comments but never saw them in the post threads. I'll be sure to keep up on my comment folder regularly in the future to rectify that oversight.
