Black Mirror has a very active sub-reddit community that pours over every episode, turning it inside out with theories, interpretations, and insights. The community and the show feed off each other and every so often the director will drop easter eggs as a hat tip to the community.
I will not spoil the plot of the episode (Crocodile) but one eagle-eyed Reddit user shared this screen capture.
The circled text on the image says:
