I think there is only one thing you can do: Leave a negative review about the place on Yelp.

The results may vary. If Yelp pays ridiculous amounts to itself for an advertising campaign, the review probably won't show up. If Yelp didn't pay for an advertising campaign, then it will show for sure.

It's not like we are talking about a particularly ethical company!
