I'm surprised to have not found a thread about it already. I guess this will create a precedent. Forgive me for posting from a puppet but the reason is obvious, my foes musn't know.
As we all know, impersonation is illegal. So is malicious quote editing. But what about forged telegrams and the like?
NS is a political game, after all. Fake documents can be used to advance political goals by causing unrest in the target region. Would it be legal to post pictures of edited telegrams (or edited offsite chats and forums, which are a separate thing) for the purpose of politics?
Another thing to distinguish is whether names are censored or not. If you're not explicitly saying person X said Y but implying it through other means is it different?
