Doesn't the digital sharing economy actually make bigotry incredibly easy to detect and verify?

All you have to do is try booking the same place on a different dates (assuming you have an account in good standing/positive reviews/etc). If they keep rejecting you, then not only are you sure you have a bigot on your hand, you have a paper trail with enough proof to go after them with a lawyer.

This is something that isn't even possible in other environments (like say, cabs that just conveniently don't see you standing there hailing them). If anything, the digital sharing economy can be a huge help to fighting bigotry.
