An awful development.

Hints:

1) Stop publishing your source code;

2) Change something fundamental in your engine nobody has that proofs a) the
uniqueness of your engine and b) a deep understanding you being a chess
programmer. When you become under attack you proof your innocence with a few
diagrams here at CCC;

3) Protect your engine with some hidden positions (and hidden code) that play
(for instance) an illegal move or blunder. As such you can identify possible
hackers of your engine.

I am glad I don't have such problems.
