I switched to a gif image for my email address and this cut spam down considerably. Plus I always use the same email address unrelated to my sites when I join programs, add links, join forums if I can.
A couple of months ago I received an email from marketing for an affiliate program that I never joined. I do remember checking out their site a while back. The funny thing is the email had my full name and mentioned my states pro football team. (My domain is registered as private.)
I RE’d and asked how they got my personal info as I’m not in their program and they just spun it saying I may have signed up for more information which I clearly didn’t.
