Dan + Shay are not happy with some people who've been selling their autographs online, and they let them know it in an open letter they posted to social media on Saturday (Aug. 29).

The rising country duo have evidently been seeing some of the same faces over and over again asking for autographs, and they figured out that these repeat autograph hounds weren't fans -- they're actually taking the signatures the guys give them for free and selling them online to real fans at outrageous prices. That didn't sit well with the duo of Dan Smyers and Shay Mooney, who responded by confronting them online.

"To the EBay sellers who camp outside our hotels, shows and airports and inconsiderately demand autographs: Please stop," they write. "We care about our fans and they do not deserve to be ripped off online. Meeting our fans is important to us, hence the reason we do 3 or more meet + greets per day."

The guys feel so bad about the fans who've already spent their money, they made them a unique offer.

"To our fans: We love you and value the time we get to spend with you," they add. "If you feel you have been taken advantage of by an Ebay seller, let us know, and we will personally invite you to a meet + greet, or send you something autographed, for free."

That kind of personal relationship with the fans will serve the duo well as they embark on their Just the Right Kind of Crazy Tour, which kicks off Oct. 1 in Louisville, Ky. and features Kelsea Ballerini as their support act.
