So, I'm moderating an old indie free to play game page (Dream Fallen Vila do Chaves) and my question is if it is ok to post download links for that game? I would think it doesn't have a problem because the game was always distributed as free to play and there's even a file in the Internet Archive that was uploaded by the creator of the game.

On almost the same circunstances, there's also another free to play game I run (Pesadelo: o início) which was also distributed as free to play but for this one I couldn't find a link provided by the creator.

So my question is if it is ok to provide the download links for those games. And if so, can I also upload the same files on other services (like, let's say, gamejolt, media fire, mega upload, and so on) just in case one of the services goes down? Or should I post only the links the creators provided?
