Want to ruin someone's day? Spoil their favourite television series

Does someone you hate really love the television series "Stranger Things"? A website will let you anonymously send them spoilers by text message. Isn't the internet age wonderful?

Do you enjoy the contempt of your nearest and dearest? Or do you have a particularly heinous ex-lover? In days of yore, you might have keyed their car. Now there is a suitably modern (and legal) way to aggravate someone or to enact your revenge. 

A website, Spoil Your Enemies, allows you to send spoilers of cult TV shows by text message – without revealing who sent them.
