Cancelled
I'm not sure we could rely on these news but at the same time, TVLINE is pretty accurate and they just posted this yesterday in their "Ask Ausiello":
Question: Camp is my favorite summer show! Any news on if it will be back next summer? —Kristen
Ausiello: I’m afraid I have bad news for you, Kristen. According to my spies at A.C. Nielsen, you are the only person still watching the show. So… no. It won’t be back next summer.
