With the relative success of my Haiku anti-spam classification, I decided I wanted to try filtering spam on Fotolife as well.
I hope to use perceptual hashing, along with perhaps OCR/image-title based Bayesian filtering to do this.
(Please note: this is a work-in-progress, and is not ready yet. Thanks for your patience!)
I enjoy Hatena's services and decided to make something to help out a bit.
