Ron Bailey, a Pocono Lake, Pa.-based broker, recently learned that a scammer scraped his Zillow rental listing and reposted it at a lower rent on Zillow, where the original listing already was. After hearing from a potential renter, the scammer corresponded through email with her, using Bailey’s name, an email address with Bailey’s name in it, and a phone number bearing Bailey’s area code, writes Inman.

The chairman of the Pocono Mountains Association of Realtors’ MLS, Malcolm Waring said he's been assured that they’re going to beef up fraud prevention. But, he added, if he learns of a similar scam perpetrated on Zillow (Z) or HotPads again, "it’s going to be the last time."
