when comment moderation fails.

So I enabled comment moderation, right? I get home tonight and I have 24 comments waiting in cyberspace to be approved or not. 23 of them are from the lovely "Anonymous" and 1 from NPR Junkie . So I highlight all the spam ones to delete, but I'm reading Becky's, and I approved all those damn spambot ones anyhow. Why do I bother?
