Scraper facebook public group's post with multiple request

[huytuchim789]

I want to scraper public groups'posts.So I try to use 100 cookies run concurrently.But after all,all cookies are invalid.I thought that they are all destroyed by facebook.I think about using a residential proxies but it is too expensive and i dont whether it is work or not.

Summary,How can i crawl 200 groups simultaneously every thirdty seconds.Can you give some advice, I think maybe it will have some api or something will work because i saw some app did that.

Thanks you for watching my question

When you use a scraper, you're impersonating a web-based normal user. The usage limits are keyed for what's reasonable for a human to do. It's not reasonable for a human to check a group every 30 seconds. I don't think what you're trying to do is possible with web scraping.

Perhaps they're using the official API. See https://developers.facebook.com/docs/groups-api/guides#getting-group-posts and https://developers.facebook.com/docs/graph-api/overview/access-levels
