"SLV (Spam Link Verification) is a service run by Russ Jones at www.linksleeve.org. The idea is that interactive sites like Geeklog or forums send all user-contributed posts to SLV first which then checks if certain links show up in unusually high amounts. In which case it considers those to be spam and flags them accordingly.
The SLV module for Geeklog's Spam-X plugin makes use of that service. See the included README for installation instructions."
