They must have had some kind of security problem. Today I received two false emails with forged disguised links asking for passwords to log in a fake site, directed to my regular audiogon account and to an older one I never used and had already forgotten about. How could this people get this email address?
They get emails by engaging into a conversation with sellers. It is not possible anymore with the new AudiogoN communicator (which is one of the reasons it was implemented), but is possible over on Audio Markt and similar sites.
I guess that over the years, they must have built a big database of emails, and now periodicaly use those addresses to send their phishing emails (to get your login and pass).
