What do you think of Spoilers?

Do you know of someone who gives away spoilers? How does that make you feel?
Sometimes if I'm getting bored with a movie or TV series, I will look at what happens to see if anything exciting will be coming up. More than not, by that time, nothing keeps my attention. For people who gives away spoilers, I'm fortunate to not have people who do that. In forums, we have spoiler tags which are extremely beneficial. I would feel quite annoyed if someone maliciously gave away stuff in a show I'm watching.

Social media is a big problem for Spoilers, its very difficult to dodge tv series spoilers. It's rely frustrating when you find out something before watching

I hate them if it spoils something I don't want to know, that is why I try to go by titles instead of reading the main body article.
