Sword Art Online: Real life identity of characters as spoiler

Not a forum post about tag names but about their wikis. Most characters in Sword Art Online are tagged and referred to by their Avatar name, while their real life identity are usually referenced on the wikis. Would like to know, should they be put as [ spoiler ]?

It is currently the case of Kirito and Yuuki's wikis. Some characters have tags for both Avatar and real life identities (such as Leafa, Sinon and Yuuki) as they have posts for their real life appearance and/or their real life appearance are considerably different from their Avatar. In Kirito, Asuna, Klein, Silica, Lisbeth and others' case, their real life names doesn't have any relevant impact in the story, but Yukki (and her sister Ran)'s real identities are understanble major spoilers (and possibly Leafa and Sinon too as their real life indetities have some relevance to their stories too).

So, should other characters' real names be displayed as spoiler on their wikis? I'm asking for advice to also organize better the list of sword art online characters.

If you think that a specific character name could be a major spoiler like for Yuuki, as you said, then you should make the paragraph as a spoiler. If the name is given pretty early in the story, then it shouldn't be one. Or if it's just obvious who this person could be.
I guess I remember that for example Leafa's identity is given very early?
