Airbnb is not a good example - it still has its own problems and controversy. But even with that said, it is nowhere near as ripe for abuse and fraud as Skip the Interview is.

Also, there's already a solution for reputation - the standard references system that already exists.

It's a ridiculous premise and would create incredibly toxic culture in professional networks.
