Other mistake: When the detective sends the traffic cam footage, a Gmail alert pops up. However, the dad is currently using Margot's computer, not his. He previously logged into Margot's gmail account on this computer so any alerts received would be Margot's mail, not his.
Continuity mistake: After David has sent his daughter texts asking since when does she not text at school, it shows he's in a video conference with some other people split onto 3 screens on his computer. The image of his boss above and the image of the 3 people to the left of David's video never changes. However, upon cutting to closer or further angles of David's video, it frequently switches back and froth from a mirrored image or not. Despite there being no reason for it switching depending on the movie's camera. (00:15:40)
Trivia: Spoilers. You can briefly see at one point that Margot's high school mascot is an anthropomorphic catfish. In internet slang, "catfishing" is when someone pretends to be someone else online in order to "lure in" others. This is a very subtle clue to the ending, in which it is revealed that the user "fish_n_chips" was a boy who was "catfishing" Margot online.
Trivia: The film is produced by Russian filmmaker Timur Bekmambetov, whom also produced the similarly-made "Unfriended." As a nod, the name "Laura Barnes" (the girl who becomes the evil spirit in "Unfriended") appears very briefly near the beginning of the film under the "trending" words during the first Facebook scene.
David Kim: I didn't know her. I didn't know my daughter.
