Factorio Forums

So I have no idea if this is allowed or not but i found a site that is giving away factorio downloads for free. As far as i'm aware, Since it is a paid game isn't this site illegal?
If someone would like the link to it ill post it but otherwise i wont.
Edit: I just translated it from Russian and it does say to support the developers by purchasing the game.

Normal piracy really. The game has no DRM so I'm sure the devs don't get too pissed off about it. It's a great game though so hey in my opinion I'd rather have everyone enjoy my game.
