An anti-pirating system.

Like if you try to start up a pirated version Geometry Dash the Vaultkeeper will give you a message like:

Wow. You actually pirated Geometry Dash? Get a job.

The game then proceeds to shake more violently than any level with a shake trigger, lagging the game and making it unplayable.
