There has been a recent one going around where the email subject says "Check it out", and in the email body, it says "Sign up so we can play". Some people actually clicked on the link in the email, and worse, filled in the blanks with their email addresses and PASSWORDS!!!
When you do that, the spammer has access to your email account, and proceeds to email EVERYONE in your address book with the same spam email.
Mr Miyagi did it, and all his Gmail contacts kena (he has since changed his password), both my email accounts kena from his one mistake. Fortunately, I ignored the emails.
I know of at least one person who not only entered her password into the page, she stayed around and PLAYED BINGO for a while, wondering why nothing happened! In fact, she played for a long time, and wondered why Mr Miyagi did not come online to play Bingo with her.
Then again, this is the same girl who, many years ago, upon receiving an email encoded with an autoplaying sound file of Mr Miyagi saying "Hello? Hello? Can you hear me?", actually leaned forward and talked back to her computer.
This is just a current version of this scam. The next ones may have a different message. But the bottomline is to be totally skeptical of sites that ask for your email address passwords. NEVER give those out especially from unsolicited emails.
And don't even get me started on the ebay and paypal phishers.
