Valve Paid $150,000 to the Creators Of Anubis and Tuscan Maps

The API of the CS:GO items, for some reason, includes internal data, among which there are such things as:
One-time payment for the Anubis map ($150 thousand)
One-time payment for the Tuscan card ($150 thousand)

The dataminer also disclosed the details of the scheme from Valve.

After talking to some map creators, Valve asks them to create a hidden skin so they can adjust the income stream from the workshop. Valve then makes "payments" in the item scheme, which are eventually tied to the workshop item.

It's a hack that allows you to pay cartographers as if they've done a skin.

Earlier, the developer of the Anubis map for the CS:GO game, Roald Roald van der Scheer, talked about how Valve pays designers to use their maps. He claims that Valve pays a certain amount for every day the location is in an active map pool, and if the developer transfers the rights to his map to the company, then it offers a one-time payment for two years of rent.
