Is it Profitable to run a GMOD Server?

The way you run a GMOD Server and the content it provides in the server will actually depict the outcome of the server

If you have great gamemode/content for players that will understand and enjoy you'll have a returning playerbase

If you have an administration team with rules in the server are set in stone where players will respect the rules and follow the concept, that will bring a good player base

If you have additional content for the server that would not be overpowered for non paying players and would just provide a small boost for paying players, that would be great
