I just don't understand why everyone else gets so infected with stuff and I see none of it. And folk who install every kind of free scanner find it all over.
I also don't get spam, and have only one email address, the same one I've had for years. Either this stuff doesn't really exist, or people are letting it in and feeding it. Or there is ~something~ I am doing right.
I'm guessing there are at least two things you're doing right: Not visiting "questionable" websites and not advertising your email address on a website.
Spammers actively "crawl" websites looking for "mailto:" html references, and then add the email address to their list of recipients for spam.
Well, spam I do KNOW exists - I get plenty of it, mostly to the email addresses that are listed publicly on my websites. I have a personal address that I keep for personal correspondence, and that stays clean. And I have a yahoo address that I use just for signing up to online things - registering for forums, newsletters, and such - and that gets a TON of spam, but yahoo has pretty good filtering, so I only have to manually delete a few message a week that get through.
