Really it comes down to courtesy. Yes, a lot of sites carry TF news, and a lot are carrying what could be considered movie spoilers - and not all of them give spoiler warning - but giving others a heads-up on unreleased fiction news is just polite IMO.

In the case of the movie, a lot of toy news does provide potential spoilers, which is annoying but unavoidable with the amount of factory leaks nowadays.

Personally I avoid any sort of spoiler info - and don't follow the movie section at all (moderation aside, when necessary) for that reason. In the case of the film, keeping movie news in that area (as intended when the section was set up) solves any potential issues anyway.
