I had to enable comment moderation due to some spam disguised as a comment.
The Britney Spears entry I posted earlier today attracted some porn spam. At first glance, it seemed rather harmless. The anonymous comment made reference to Spears' going commando and how it's a cry for help. Her name hotlinked back to some porn site. They then referenced the porn site directly, where we could find many more photos of her in her state of crying out for help state. Had they linked to specific pictures or articles associated with the reference, I may have left it.
Live and learn. The moderation shouldn't be a problem since I have yet to receive any other comments for my entries. :)
