I think this may be the wrong question. I am the administrator of a reverse engineered PS3 video game server, so it’s illegal for me to make a profit or any kind of revenue or donations from that platform. However, I maintain it for thousands of users simply because I and others enjoy it and want it to exist. That’s not a sustainable model for a business or for running something as gigantic as reddit, but it’s what I want and enjoy, and for right now it’s affordable, and I’m happy with that.
