Can't sign in – JibJab: Funny Cards & Videos Review

Should it be this difficult to sign in to an app like this? Signing in with Facebook requires an account to then be set up. I enter my email address and it says it's been used already. I select Forgot Password, enter my email address and it says that address isn't associated with a JibJab account. What? Why the Facebook "sign in", just to steal my data? Deleted.
