tty stands for TeleTYpewriter.[2]
Usage
The tty command is commonly used to check if the output medium is a terminal. The command prints the file name of the terminal connected to standard input. If no file is detected (in case, it's being run as part of a script or the command is being piped) "not a tty" is printed to stdin and the command exits with an exit status of 1. The command also can be run on silent mode (tty -s) where no output is produced, and the command exits with an appropriate exit status.[3]

gollark: Actually, do those support adblockers generally? I have no idea. Get one which can do adblocking.
