My 80 year old mother got some spam that she had won $500 at an online casino. ~sigh. She went there like a bat out of hell, gave 'em all kinds of info and now her emails are full of spam.
I worry about my dad with things like this. I set him up with his first computer and DSL last year. I check with him every week or two to be sure he did not get fooled by some phishing scam.
I'm not so worried about him getting on a spam list - I fear him getting tricked into giving out is SS# or bank account number.
