I want to scrape comments from a public facebook page (news network) through the facebook graph api. However it says i need to create a app to do this.
After a bit of research I found out that facebook prohibits web scraping since the cambridge analytica scandal.
Is there still a legal way to scrape data from facebook? Does somebody here have experience he/she can share? Thank you in advance.
It is possible, but you have to create an App and apply for Page Public Content Access: https://developers.facebook.com/docs/apps/features-reference#reference-PAGES_ACCESS
...after that, you can get the feed of a public Page with the /page-id/feed endpoint, with an App Access Token.
I dont know about the legality of scraping facebook, but you can use a library called facebook_scraper
for instance:
from facebook_scraper import get_posts
for post in get_posts(name_of_your_public_group, pages=10):
print(post['text'],'\n')
Note: working only for public pages
