It seems he would call around to all the hotels in a city where she was broadcasting a game (time for broadcasting crews to start using pseudonyms...figured they would have been already), then request a room next to her (which apparently some hotels would do?!), then modify the peephole with a special camera.

They still can't figure out which hotel one of the videos is from.
