Valve’s Operation Payback lets players gain access to seven of the most well-known community-created maps in CS:GO. Each pass costs $5.99 and all proceeds go directly to the map creators.
Since Valve implemented Operation Payback in April 26, it has raised over $150,000 for the CS:GO community map makers.

According Valve, Operation Payback is “first of an ongoing series of limited updates aimed at rewarding CS:GO’s most popular mapmakers” so we can probably expect more of these kinds of initiatives in the future.
Operation Payback passes can still be purchased but only until the end of July. They are currently 80% off on Steam. The seven maps include Museum, Downtown, Thunder, Favela, Motel, Seaside and Library.
