Induane, mountains out of molehills.
People can run a server with PS art to take screenshots, or explore the world on their own. They can run a server to test what the GM commands are like. I've encouraged it during all my time here, and so have many other devs. It's really not something to pick at. Moreover if it actually becomes an issue, I'll further encourage people to say they're testing something locally to see if they can help the team and that's their excuse ;)
