Thanks very much. I typically REJECT a spammer, but when a block of IPs 
start showing up, I GreetPause them with a higher number. Once I know 
the entire Class C is bad, I REJECT that and remove the GreetPause along 
with the individual IP REJECTions. I'm not sure I was doing any good 
with the GreetPauses, but you seem to be correct when you say they wait 
me out, which would explain it.
