Show HN: Yelp is breaching privacy rules

So I went to Yelp and it showed me bar as shown in the screenshot. I have never logged into yelp using my facebook account. However, I am/was logged into facebook on the browser. Yelp decided it was ok for them to log me in WITHOUT asking for my permission/authorization.

Also, in the app centre, it was already added there as an App I authorized. I checked this with different facebook accounts and the same thing happened. This is really f*ed up!
