Seen one or two of these myself...Phil can you do a screen shot of one and post it?
Another test of suspicious email links is to put your cursor over the link and look at the address in the your lower right browser tray, you'll see it is not going to a VRBO address...that may not be the easiest thing to understand but its how I check suspicious emails (theres another way as well but the chance of triggering the link is much higher so i won't discuss that one) ...I consider myself pretty savvy to Phishing schemes but its gotten to the point where these are so well counterfeited I've even been fooled, but fortunately only to a point...
A more recent scam for VRBO is for a telecamera to collect your phone number from the listing then call you claiming to be a "travel agent" representing a group wishing to rent your place. Do not give out your VRBO email address as that opens the door to phasing schemes. Instead tell the "agent" that the group can make an online inquiry as per normal VRBO procedures..that frustrates the hell out of them and I was actually beginning to have fun with the jerk when he finally hung up on me...oh by the way since I took the call on my VRBO cell I was able to see that the "Travel Agent" from "London", Indian/Middle Eastern accent, was actually using a Skype account based out of Los Angles...
