I have a "special" e-mail account that I use for logging into sites that REQUIRE login. It's for real, but I only log into it once a month or so, just for kicks.
Surprisingly, I get NO spam from the Trib what-so-ever. They don't send me a darn thing. Of course, I only gave them they absolute minimum of info, and check or unchecked any boxes about "getting e-mail from our sponsors" and so forth.
Most companies realize that SPAM is not the way to go...
The most spam I get is from Dell, but that only came after I bought a couple of computers from them. They don't send e-mail out all that often though, and it hasn't been all that much of a bother.
