Stumbled upon an old screenshot of the admin panel I made for GunBound Classic many years ago. This is an example of how we could tell if a user was fixing games.
Another old screenshot, this time how we moderated the freeboard on the main website. Also a good reminder that deleting anything doesn't necessarily mean it's actually deleted.
If you were IP banned, you were prohibited from viewing the website, and the game's patcher would fail on you, preventing you from logging into the game.
