Well, most likely impossible. I’ve noticed a lot of requests for spoiler tags in Cafe Society until the show airs everywhere. I had a cwazy idea to have people be able to set expiration dates/hours on their spoiler boxes so that they would not appear after the expiration date.
So it would look something like:
[spoiler=24hours]Rosebud was the name of the shed[/spoiler=24hours]
and that wouldn’t show up until 24 hours after that post was made.
