But SBL aside, it can be difficult to successfully identify the true bad guys using the above without catching too many innocents in the same net. That said, I use several of these other RBLs myself. I'm not necessarily opposed to them, but feel our approach with SURBL *adds* something hopefully new and effective. Jeff C. -- Jeff Chan mailto:[EMAIL PROTECTED] http://www.surbl.org/
