Musing Monday - On Spoilers

Musing Monday is a weekly meme hosted by Should Be Reading.

Why do people spoil books? Do they get a perverted sort of satisfaction when they spout out spoilers - major and minor - to destroy the reading experience of fellow bookworms? Don't they realize how sacred reading is to the reader? 
A reader's journey is personal. Of course, we share our experiences, and our opinions on books. Of course, we passionately discuss books with others - debating over the newest plot twist, who's going to end up with whom in yet another love triangle, and our absolute favorite: which character(s) is going to die in the end. But spoilers?
Spoilers are a different thing altogether.
Revealing major parts of a novel's plot on the net, leaking them out and ruining the book for readers caught unawares, is NOT cool. 
You know what? It should be made illegal.

For those bookworms who have gone through similar suffering, here's an Wikihow article that might help.

I bawled my socks off for three whole days after the spoilers. They were DEVASTATING, to say the least. Please, please - for the sake of humanity and all that is good on this earth - avoid spoiling books (and movies and television series) for other fans. And if you're acquainted with a spoiltroll, beware.
