Mike,

Since we removed the email feature here we have noticed an increase in members joining then using the sitemail system to send spam. This one you got had already been reported and taken care of.  I think the "spammers' used to use the email feature here since you didn't have to be logged in to do that but since we removed it then I think they still think they are sending actual emails but its not, its instant message and if someone replied to one of these, they wouldn't get their email address just username which they had to send the sitemail to begin with.
