But it's not poison pill, the score can be 3, 6 or 9. Some spams will only have one of those hits. A lot of ham using those TLDs will hit two or three. > In the future I'll omit the score lines when I post updated REs. > Everybody: take the scores for these rules (same as the scores for > *any* rules posted to the list) with a grain of salt. What I'm saying doesn't have anything to do with the rule scores (as long as the individual scores are below poison pill level). The point is that the distinction between the three score levels is based more on noise than real information. The way you are doing it relies on very little ham using these TLDs, and constant vigilance to make sure that doesn't change. For the same current TP rate, meta rules should degrade more gracefully.
