For some secret purposes is required to collect this information from Facebook profiles: date of birth and mobile numbers (if present). I know, that this information is visible only if it made public by the user. Anyway, interested in finding such profiles and grab that info. I've searched by google or some crappers or just manually and cannot find any reliable solution or hint. Maybe someone came across similar task and could advise (at least some ideas) what to do and is it possible to automate by google search, php script or something else.
