If you have a score to settle with someone or you are simply evil, the application Spoiled.io is for you. For just 76p, you can anonymously send any of your contacts huge spoilers for the latest Game Of Thrones episode as soon as the show has aired in the US.
This application sends a message from an unknown number so that the recipient can't tell who the spoiler has come from - but you get to see their responses.
Not content to spoil the plot for unlucky fans, Spoiled.io publishes the responses of their victims on Twitter, as well as sending them to the sponsor. The responses range from anger, confusion and despair - but they're often pretty hilarious too.
This service started up back in June 2016, just before the release of the last episode of season 6. The creators explained that this idea had come to them from a Reddit thread, where a woman got her own back on a cheating ex by spoiling the latest episode of Game of Thrones every Monday before he had time to watch it with his new girlfriend.
After two years of waiting to see the final season at last, fans will be more afraid of spoilers than ever. So, if you receive a message from an unknown number on a Monday morning... beware!
