An off-topic post…
Apparently I have a high enough Page Rank that spammers love my site. I actually have two different anti-comment-spam plug-ins running on my WordPress installation. But lately there are been hundreds of spam comments per day that the system can’t decide are spam or not, and so it offers them to me for moderation. I just don’t have time to sort through them all, so I simply delete them.
I haven’t heard any complaints, but if your comment falls into the pit of false positives, my apologies.
Update: I installed another WordPress plugin that asks you to answer a simple math question before posting, and this seems to be working perfectly so far.
