Open a hotmail account, never use it, but check it once a month, and watch what happens.I've got one for that purpose - I only use it as a landing pad for my MSN groups. I generally get anywhere from three to five messages a day on it.
Thanks to MailWasher, I end up deleting them automatically.
I have an email address in express that for the last year has gotten a total of 3 messages all 3 came from my ISP about services. Not one piece of spam.
I have a main account that gets only responses to those I send out.
Then I have the one I send when it asks for email address... it gets 3 - 5 spams a day.
