I never read any spams except the one that tried to sell me land from the moon - that was funny. Also those Nigerian bank scams are funny like hell. I have read that many companies have paid and lose their monies. Right for them. If you're fool enough to believe that someone will actually send some $20 million to your bank account, you're fool enough to believe they need that $4000 you send them to do it.
Some spammers try to be clever, they use titles like "re: your order" - nice try but no cigar...
Some looks like idiots, use titles like "hi, me here". Must be newbie spammers...at least those who post with male name...
I delete all spam first thing every morning. I don't use any blockers as I don't have it a lot, but if it increases, then I will.
Here in Finland spamming is a treason. No finnish company or individual can spam. If they do, I just call the cops.
I hope someday it will work world wide.
