Opinion:

I would suggest you speak to a lawyer if you are that concerned about it. I am not going to provide legal advice.

If this is illegal, do I think that's a bad thing you are experiencing? Yes. But your choices were to either keep looking elsewhere or accept it. You chose to accept, and from the sound of it, so have many others. The world is what we make of it, for better or for worse.

And I'll end my thought by saying, that silly old law, become a silly old law, because the world accepted it as such.
