@valerauko persistence is key. Or maybe a gun, if you want fast results.
If you'd like a pacifist route: create a bot to parse the most popular series of the moment on imdb, extract the sinopsis from Wikipedia (which is full of spoilers) and sent it by every social network you can think of until they say they already tested it (bonus: make them fill a questionnaire which stops the bot if all answers are correct)
