Kip Moore is sounding off about something he is angry about -- ticket scalpers. The 'Dirt Road' singer wrote a hand-written letter, expressing his frustration with scalpers, which he posted on his Facebook page.

"I watched my dad bust his ass for not a lot of money while supporting 6 kids until we were able to take care of ourselves," he begins. "From 18 to 31 I lived paycheck to paycheck working a lot of long hour jobs for very little pay. I know what it’s like to live on a strict budget and wish you had funds to take your girlfriend, boyfriend, husband, wife, friend, daughter, son etc. to a show or a game but you just can’t afford to."

The 34-year-old goes on to share that his own humble beginnings are the reason he keeps his ticket prices so low.

In the long letter, Moore shares a few things that upset him, including Congress, rising gas prices, selfies, political correctness and more.

"But above all, the thing that pisses me off the most is scalpers," Moore writes. "I could sit back and ignore it, because I know it’s a losing battle, but I just can’t do that. People are trying everyday to fix this problem, but it’s a difficult task. I’ve recently been told that it looks as if some people who bought the pre-sale tickets are turning around and putting them up on different sites for much steeper prices."

The 34-year-old urges his fans to buy the tickets as quickly as possible, to avoid them getting into scalpers' hands, before addressing the scalpers directly.

"To those of you scalping," he concludes, "I understand doing whatever you can to make a dollar. I also understand there are ethical ways of making that dollar. Twist it however you want to make it to seem like what you’re doing is ok, but it’s not. I want to always keep prices low, so don’t be a d---."

Moore isn't the only country artist who has spoken out against ticket scalpers. Eric Church has also expressed his outrage over the system, going so far as to re-sell seats purchased by scalpers to "make it harder for them to remain in operation."

Moore will kick off his headlining CMT on Tour: Up in Smoke trek this fall. See a list of all of his upcoming shows here.
