The thread has absolutely not the purpose of being used by anime only watchers.
This is really the most spoilerish thread that should be used for everyone who have access to all content, or for those who wants all the spoilers.
And you are forgetting that this thread does NOT take the purpose of
[Anime] Umineko - Speculation & Theories (for first time viewers and
[Anime] Umineko - Spoilers & Expectations (for experienced VN readers only).
This is why I tagged [game] for the newly created spoiler thread.
I absolutely don't see the problem you are exposing, especially that I did mention that speculations and theories should be left in any of the 2 threads I've linked, depending of the content, NOT in anime episode thread (they are solely destined for comments, critics, etc).
