The Facebook fan page for Pittsburgh Tactical Firearm, the owner of which has been running a giveaway contest for an AR-15, has been inexplicably closed — along with a second page that the owner started as a replacement for the first.

“I still don’t know what’s going on,” gun shop owner Erik Lowry said in The Blaze. He noticed the page was shut three days ago after hundreds of the page’s 27,000 followers called and emailed to ask what had happened. He tried to put up a replacement page, but that one was shut down, too, he said, in The Blaze. Mr. Lowry said he’s since asked Facebook officials for an explanation — at least 100 times — but to no avail, The Blaze reported.
