Because it's the same thing as sharing private messages. Those are meant to be private and not be shared without the other party's consent. So give a link to a message someone said publicly (such as on the forum, or some social network) is all good, but revealing a private text isn't. Same idea about public and private replays.That was a massive help, thanks a ton! And thanks Boat ;D
Out of curiosity though, why is linking someone a public replay midgame allowed, but not a private one? Since you mentioned that before the game starts, both would be acceptable ressources
