Bob The only sure way I have found to keep the spammers at bay for several months (even with ISP filtering) at a time is to change the format of my basic email address by inserting/moving numbers in place of letters when I begin to see a buildup of that junk.
That, in turn, requires me to change a lot of reflector info. IMO, If it ain't broke, don't fix it. I can find most, if not all email addresses I might need either on QRZ.COM or through the FCC data base. Phil, K3IB > deleted as requested >
