Both RottenTomatoes and TripAdvisor require me to authorize them on Facebook before they show me any social data. Are you sure you didn't authorize them in the past and forgot?
- TillE 14y agoI'm almost certain that RottenTomatoes will display your name if you're logged in to Facebook, regardless of whether you've given them permission. I remember being disturbed when I saw that recently, and immediately sought out and installed a social widget blocker.
- thefreeman 14y agoIf that's happening the widget is most likely an iframe loaded from facebook, and not accessible to the RottenTomatoes server
- wilfra 14y agoNot 100% certain, but nearly. They were just two examples I could think of off the top of my head though. As the other commenter said about TWP, the practice is common. I see my name and other social data displayed on sites I've never signed up to regularly.
- paulgb 14y agoI see that too, but in that case the social data is served from Facebook and doesn't go through their server unless you authorize it. Unless there are exceptions I'm not aware of.
- wilfra 14y agoSo when I see a Like button on a site I've never visited before, that displays my name, FB avatar + social data - you're saying that the site I'm on has no way to know that I've visited it unless I click the Like button? Only Facebook knows that and is displaying it in a way that is undetectable to the owner of the site? This is a bit over my head programmatically but that doesn't seem possible. If Facebook is serving something to visitors on my site, surely there must be a way for me to capture that data?
- gnaritas 14y agoNope, that's how iframes work, you can see it, but they can't get at its contents. Cross domain scripting isn't allowed in an iframe.
