How sending this. "{enter}WW3S WW3S ". Maybe this would break the association between the CQ from AA5AU and you better and not spot you. I seem to rarely get spotted during S&P and this is what I do.

Quick fix. Don't send the 'DE' before your call. It is absolutely unnecessary!

What I think usually happens is the skimmer cannot tell the difference between who is who.....so since most people now append their CQ message with CQ, it goes like this.... 
CQ AA5AU AA5AU CQ 
and then I answer 
DE WW3S WW3S 
ends up looking to the skimmers as 
CQ AA5AU AA5AU CQ DE WW3S WW3S 
and I get spotted on Dons run frequency.... 
just a semi educated guess, from a semi educated man....
