So, you’ve reached the end of a game or just watched the finale of a popular TV show and now you want to share your experience with others on Reddit. Should you do it? As fun as it is for you to share what you just watched on Reddit, others in your community might not take kindly to your post/comment.

To prevent others from being caught off guard, but still allow you to post your own content, Reddit offers a number of spoiler tools. These warn others of spoilers and hide some of the content you think might ruin their experience.

Spoilers are intended to help others viewing a post or comment avoid content that could reveal information about something they themselves might want to learn as a surprise. For example, if you’re in a subreddit dedicated to an ongoing TV show and you’ve posted bits of content that could reveal a scene from the latest episode, others won’t find it funny to see this info within the community, because you could ruin their viewing experience by taking away the fun of the surprise.

Because not everyone wants to know what’s going to happen in someone else’s movie or TV show and would rather see it for themselves, Reddit gives you all the tools you need to hide your spoiler content behind an extra click. It’s part of Reddit’s unwritten etiquette that many users follow when they want to share their thoughts on something they’ve recently seen without making it awkward for those who don’t want to see it.
