Facebook

If you block someone on Facebook, you'll still be able to see things that person has created within an app, but you shouldn't be able to interact with that person and they shouldn't be able to interact with you in the app.

Keep in mind that apps aren't built by Facebook and are operated by outside developers. If you're still able to interact with someone you blocked on Facebook within an outside app, you'll need to contact the developer of the app.

Facebook isn't responsible for the support provided by developers, but we work to make sure that all outside developers are following our Statement of Rights and Responsibilities. If you find that a developer isn't responding to your questions, please report the app.
