Ask HN: Are there ways to harvest FB group and subreddit content?

I'm trying to learn more about expat life in Crete, Mallorca, Roatan, ...

Facebook groups like "Expats in Mallorca" are a treasure trove but rather unfriendly to skim through as a human reader. Similar for subreddits.

I was wondering if there's a way to scrape and feed the content into an AI platform which can then summarise it?

Next to technical challenge, it's probably also against T&Cs to scrape data from groups so are there any "legal" solutions?
