(at around 12 mins) At the beginning when Blaire is messaging Mitch, 2 messages in a row disappear, and they write more, then the 2 messages reappear in the correct place again.

(at around 58 mins) Adam goes from holding up 3 fingers to 4 fingers then 3 again during the game "Never have I ever".

(at around 1h 14 mins) On Blaire's Facebook page, the thumbnail of her friend Tony changes to a different person (Ryan) at the last shot of the page.

(at around 50 mins) When Blaire forces her browser to quit, all windows displaying the YouTube video closed, but her original session remained open.

(at around 1 min) In the beginning of the movie, when Blaire watches the Laura Barns' suicide video on LiveLeak the timer under the video says that the video lasts 2:30 minutes, but when she puts the video on full screen. the timer says 1:59 instead of 2:30.

(at around 29 mins) Initially Blaire shares her entire screen to everyone to show the "EXPOSURE" link but she didn't unshare it and she still messages to Mitch privately. But since the screen is shared it should be visible to everyone.

(at around 50 mins) In the scene that shows a YouTube video, just before several more pop up and cannot be closed, the two time indicators (total video length and current position) both are changing. The display showing the total video length should not change as the video is played.

The film, which happens on a Monday, states that Laura Barns' date of death was the 12th of April 2013. If the film is set on the 1 year anniversary of her death, it should be a Saturday.

(at around 50 mins) There are more more dislikes to the Laura Barns Kill Urself video than views.

(at around 38 mins) When the pictures where sent to Blair from Laura, the first picture, which was just under 1mb, took a lot longer to download than the second picture which was just over 1mb. With an internet connection being able to stream 6 calls at once, downloading a 1mb picture shouldn't take no time at all.

(at around 36 mins) When Blaire opens up her browser to look up police radio codes, the link is purple while the rest are blue, meaning that she's already been to the web link before in this browser cache cycle, but it is unlikely she had any reason to ever do that before.

The video that caused Laura Barns to commit suicide shouldn't even be on YouTube in the first place as one of the policies on YouTube is for bullying.

Adam had no reason to admit he slept with blair.

Instead of unfriending Laura. Blaire could've blocked her.

(at around 18 mins) Immediately after Blaire unfriends Laura, it says that they are friends again. When Blaire types "problem solved" in iMessage to Mitch, it says "Friends" instead of "add friend".
