People from different instances are not able to login on your instance. For example you might see me in the people table, but local should be false. People registered on your instance shows up on local_users and on people with local set to true.
There have been mass registrations going on recently. Imagine my surprise when my 3 people instance had 460 users but no one online today. Took my instance down to investigate and deleted all local users in person table except the known users. Not the cleanest way to do it but I don't think I broke anything :D
I was about to buy this but apparently they are planning to change their current anti cheat software to FaceIt which does not support Linux. EAC is still used for upcoming selfhosted servers but ranking up is disabled. I'd rather not feel like being considered as a second class citizen so I'll have to skip for now.
Other than that the game looks fun. I prefer to look in to the current state of the game rather than the promises of future content (which kind of contradicts my anti cheat point but eh), and I feel like the current price would be worth it even though it's an early access game.
