By nature, this site is where we ask questions from both manga and anime. However %90 of the time, anime is behind the manga so asking a question from the manga can be considered as a spoiler for anime-only people.
A small example would be:
Why the character X is doing Y?
The problem is, in the anime we still don't know X and now we are sure that X will do Y.
Now there are many discussions about this I am aware but none of them is conclusive. Some are against it, some say it's fine. Others say we should try to do it without spoilers but if we can't then it's fine. Is it really? Let's imagine a scenario where a member of the community checks the questions daily. Then bang, he sees a spoiler from a show he is watching. He clearly did nothing wrong but the person who is seeking an answer didn't either.
Some examples from other discussions:
Thus my proposal is as follows:
We should clearly imply that the question itself is a spoiler. An example would be like:
[Show A - Manga Spoiler] Why the character X is doing Y?
With a standard like that, at least we can create a middle ground for both of the sides.
