I was not sure if they are serious or not until I read the FAQ:

> Q: Is this legal?

> A: We operate in a legal gray area that our lawyers describe as "innovative." Our terms of service are 847 pages long for a reason.

> Q: How is this different from stealing?

> A: We prefer the term "aggressive recycling." Think of it as the circular economy for API keys.

(and then they spoil it at the end, too)
