I have a couple of autoblogs set up, mostly with wp-o-matic and syndic8 kahuna. Like most of the other people I get Spam Karma emails several times a day asking me to moderate comments. I just ignore them now and delete the emails. Would I be better off just turning off the comments? I would think it might be possible to fill a MySQL database with comments waiting to be moderated. I wouldn't want to waste the space that could be used for more autoposts.
