In reply to Bigwas.

Sorry, I don't agree with that. I often get anywhere from 20-60 comments on a post (sometimes in the hundreds), and I don't manually approve, they're all approved and I moderate after.

I rarely have an issue with spam, as I use an excellent plugin that counters almost all scripts, and the comments that do get through, I simply block the user. Moderation is only a pain if you let it be.
