Wait, you mean spammers are sending spam to users without first making sure the users opted in? This is happening? Say it ain't so! Next thing you know, they'll be using forged return addresses so you can't figure out who they are!

Oh, wait...

Incidentally, Popfile (a free program) is currently "eradicating" about 97% of my spam, and they don't send me any spam to tell me about it, either.
