Is it impossible to get the hashtag data from FB graph with V2 , or other ways or methods to do it ,hopefully this question is not very hard, Thank you for your patience if you have read my question in the end.
PS: For FB graph V2.* I am afraid it was provided HASHTAG data's ,however Can I get it by paying money ??? thanks again
so now, I knew FB can not offer any resources to public place.
Since v2.0 it's no longer possible to search for public posts, so: No, it's not possible
