Question about the 5% royalty

[zeOrb]

What I wonder about the royalty scheme in general:

How does Epic know Im making money with an UE4 game?
The scenario: I use UE4 and develop a game. Then another person publishes and sells it. We share the revenues.
How would Epic get to know about that? I mean, they cant possibly know of all games that are released everyday worldwide…
And is it possible to verify from the packaged game that it was developed with UE4 and which subscriber?

It’s not very hard to track down illegal use of engine and if legal team will find out about such project - this will happen
