I've been using Spam Karma 2 for a while - it works great against spam and I've NEVER had a spam comment get past it since loading it onto my wordpress powered site. Sadly, I had a different kind of comment problem - from actual people posting profane and insulting comments ad nauseum on my site, and I was forced to allow comments only from registered users, and disabled open registration (effectively giving only two people the power to comment, my own admin account, and one of my contributors/friends). Since then no one has been able to comment besides the two of us - until a few days ago. Without changing any options, I've seen SK2 harvesting a few spam messages a week now. Do you have any idea how they could be getting posted when comments are disabled from non-registered users? They are not coming from any registered account (ruling out any potential password leak). Any insight you could offer would be greatly appreciated!
