From M'Sharak's cautionary thread
over in the Star Trek XI+ Forum
Additionally, you'll want to be sure—outside of the Trek XI+ Forum—that you don't casually let slip plot details, post images depicting plot details or wear avatars which depict plot details. All of this really amounts to nothing more than having a little common courtesy for your fellow posters; if they want to watch the movie knowing nothing in advance, then they ought to be allowed to do that.
This is the way it is to be done.
Learn it. Know it. Live it.
If that big ol' spoilery Trek XI+ forum isn't enough for you and you just can't stand it and have to to drop hints in here, we would appreciate it if you would please use spoiler tags.
Your humble moderator is one of those people who wishes to stay unspoiled about the next Trek movie, so I'll be all over this like a cheap suit. Have a heart, okay? Thanks.
