There is a difference between promising a unicorn and having a proven track record. That you are too lazy to verify the background your potential hire is providing you is 100% your problem. Bite me.
If you don't know how to do background verification on people then you have far bigger problems than your fears of being gamed.
What I am saying is: I think you know and you have an agenda.
If you truly don't know then this is really something you should know if you are doing the job you are saying you are doing.
To use an analogy: I would not waste my time explaining how type systems work to someone who is arguing rabidly against them in an online forum.
If they care then it's something that is so important they should actually go out and educate themselves before getting into conversations about it.
