May be you are thinking of what is "Don't Share This" button?Yes,i was also asking this question to myself when at first i saw this in web.But this is true.Netfilx an online American provider of online internet streaming video and united states has used this button in their application this "Don't Share Button" and used the logo of Facebook.
It was at first discovered by the iSmashPhone which reports that the popup both in iPhone and iPad window shows this Facebook "Don't Share This" button.Now this is no more visible in those application so this is now hard to tell what actually happened.
Many accidental things happen when companies upgrade or change their posts or website.But this type of accident can cause a lot of dollars damage of the company.Hope this is an accident and Netflix is not penalized for this.
Further updates will be posted here.
