Edit: Okay. Perhaps require folks to answer an email or a captcha to activate their blog?
I figured it was something like that.OK, figured it out. It was set to subscribers only. I was wondering why, and switched it to all registered users, and immediately we got hit with a hundred or so spam blog entries. That, I guess, was why.
So I've switched it back; sorry. I have to find some way of blocking those blog spammers.
