The GNAA is sending out IMs telling you that your password-protected posts have been stolen. This is a bluff; no one has stolen anything from you in this case. The link they send you to contains a Java exploit and is dangerous. Do not click it or link it to anyone else.
Could be old news. Oh well!
Mucho appreciado
