I took James’ advice and populated my whitelist for Referrer Karma. Before I cleared the tables, I added whitelisted items that came up in my logs in addition to my blogroll. Hopefully, RK checks known-good sites less, and putting more focus on questionable ones. I may be tired right now, but I can’t remember the last time I had comment or trackback spam – and I definitely think RK + James’ moderation word list helps.
