get facebook posts (and older posts) without access token

i already found a way to get posts without an access token: http://ift.tt/19AfinE http://ift.tt/1EqmUae

With the URLs above you can get the newest posts, but what about the older ones? I basicly wanna achive what facebook already got (load the newest posts and then there will be a button "load more"). Including an IFrame is not an option. I want to make the facebook posts responsive.

Does somebody know if theres a way to get the older posts? I already tried adding &offset=10 but it doesnt seem to affect anything.
