and hide things with warnings that you don't want people to see or read. For example, say I'm discussing an anime and I spoil it.
With spoiler tags, this won't happen!
Encrypted transmissions will have more depth to them as people won't click on SUPER SECRET TRANSMISSIONS and just see the SUPER SECRET message glaring at them in the middle of their face.
(Idea) People can use swear words and other "inappropriate" language with a warning and a spoiler to mask their content for eyes who are too young. Then, it's not our fault if we stain their innocence.
