Reasons to use CW
1st - this is fuzzy, don't expect tidy rules.
- upsetting material (unless being incendiary is your thing)
- off topic material if you think your audience is mostly single topic readers (if you are multi topic all the time, why bother)
- Looooong posts
- clickbait - Guess what just happened?!?!?!
- a halfway point between self censoring to avoid fighters and looking like you're picking a fight
