Its a matter of fact that published rules (see sare rulesets) become less 
effective immediate after publishing. That due to spammers reading along 
ect ect.

I can understand Dallas point and dont agree that making this open will 
give the same results.... It should, but it just doesnt.

We have rules very ok hitting, and i know once we put this in a SARE set 
the effeciveness will drop and we have to come up with new rules. Not 
really something people look forward to. Its just a handfull people 
contributing as you know.
