The titles for spoiler threads must be kept relatively ambiguous. This means that character or plot points should not be revealed in the TITLE of the spoiler thread. This is to protect spoiler-free members from getting spoiled while using the forum's 'lastest posts' features.
For example. Instead of:
"David Jones to be revealed as Olivia's future son in finale!"
Something like the following would be OK:
"Major twist involving Olivia and past villain to be revealed in finale"
Note: This does not mean that spoiler posts can be posted outside of the spoiler section with spoiler-lite titles.
