How has my email address leaked out?

Spammers get people‘s E-mail addresses a few ways. 

1. They illegally buy lists of real e-mail addresses.

2. They use harvester programs that scan the internet. 

3. They use hacking programs.

4. When you click unsubscribe links you unknowingly let spammers know your address is real so more spammer will spam you.

Somebody in Canada must have found out I used Viagra once. My e-mail was hacked and I got locked out. That was two years ago. There must be a billion Viagra ads in it.
