I am building a Facebook application which should not be viewable to anyone under the age of 18, as it makes quite extensive use of the Graph API I wonder is it possible to automatically find the age using that.
Looking at the documentation I can see that it should be possible to find a users age-range using signed requests. However I've not managed to find any actual examples of how to implement this.
Ideally I'd like to be able to end up with a variable which had either TRUE or FALSE as it's value. True being over 18, false being the user is under-age.
I contemplated asking for birthday permissions and calculating the age using that however it seems that many of my friends do not show their birth year so I assume many others do the same, I'm guessing that if the birth year is hidden it will not be accessibly to the Graph API.
Could anyone help me with this?
Thank you.
