Be careful what you put online. If the recent NSA scandal has taught us anything, it's that someone is always watching. Now, two separate cases of boys writing threatening, albeit sarcastic, remarks online have quickly gained a lot of attention after both boys were thrown in jail.

19-year-old Justin Carter of San Antonio, Texas has been in prison since February over remarks he made on Facebook while debating with other people over the popular online video game "League of Legends."

"Someone had said something to the effect of 'Oh you're insane. You're crazy. You're messed up in the head,'" Jack Carter, Justin's father, told CNN. "To which he replied 'Oh yeah, I'm real messed up in the head. I'm going to go shoot up a school full of kids and eat their still-beating hearts,'" appending the message with "jk" for "just kidding."

Since his story first broke, Carter has received a significant amount of support from people who think his treatment has been grossly unfair. Carter is currently in prison on $500,000 bail and could be sentenced to upwards of 8 years in jail. This past month Carter has been on suicide watch as he's grown despondent over the situation.

"The law enforcement, the sheriff's department, the district attorney's office -- nobody wants to be the one that let him go," his lawyer Donald H. Flanary said. "They don't think about the person or the crime or the lack of crime ... they don't want to take responsibility for something happening in the future."

Carter isn't the only one, however. Josh Pillault who was 19 when he was arrested last October in Mississippi for a similar offense, when he threatened a player while playing the video game Runescape. He had been told to kill himself by an antagonizing player, and from there said he would kill not only himself, but take the whole school with him.

"His doctors have said he wouldn't hurt himself or anyone else," his mother wrote. "We actually have teachers who were willing to testify that they knew it wasn't a true threat as soon as they found out it was Josh. Even his fellow inmates and guards have commented on how they can't believe he is still in there."

Still, Pillault was kept in prison despite maintaining his innocence. Eventually he was advised to plead guilty in hopes of getting a lighter sentence, as his case was looking increasingly grim. Now, he's facing up to ten years in jail and a fine of $250,000.

"Instead of being home with his family, he spent his birthday and the holidays behind bars," wrote his mother. "We all worry about him constantly. I barely sleep anymore because I am worried about him."
