It's really hard. Depends on what kind of info do I know, the relationship with the devs, like, why would I even come across unreleased info? Because I have a connection to someone? Because I stole it? Because they sent it to me by accident?
If they sent it to me, I'd most likely believe they've sent it to everyone else, so I'd probably leak it unaware that I was leaking secret info. But it depends on the game. If it's a game I don't care about, surely I wouldn't even bother to tell anyone about it. But if it's a Pokémon game, for example, it would be very hard for me to keep quiet, but I'd try to wait until someone else reveals it. Maybe if I see near the release date that no one has talked about it, I'd share it. Or maybe I'd disguise it through a random post on 4chan or something.
If I don't have a close connection to any of the devs, I'd probably talk about it in some forum, just like, "hey I heard this and that, but take it with a grain of salt" and just wait for it to be proved true or false. But I don't think I'd leak like, images or footage, like if I had the actual game. But if I have a blurry image, I'd probably do it :P
