Re: Yet another splog question…
Maybe we should ask this question in a spammer’s forum 
Andy Peatling once told me it was more of a WPMU problem (are you using WPMU?). But I have also heard people reporting the problem only arises once BuddyPress is activated. I don’t know, sorry.
I reduced Sploggers to about 20 per day, which is OK for the time being to handle (but of course quite annoying). Looking forward to solutions – as we all are, I guess. I can’t imagine anyone not having this problem – since I have so much spam on a hardly known site.
