Some very small but non-zero percentage of this is not in fact spam. So I used to scan everything in Akismet's grease trap, in order to rescue the real stuff. In the past, I've salvaged worthwhile contributions from John Cowan, Language Hat, and others. However, the volume is now so great that I usually don't have time to do this. If your genuine contribution is trapped and flushed, I apologize in advance — let me know by email if you think this has happened.
