It is difficult though, even if you will check every single post of the facebook page just to confirm if it is true, you still can't guarantee by that way.
Also, if he/she is one of the founders, then some founders or people on the charity may testify or prove if that person is one of the founders and telling the truth.
I know that doesn't guarantee it, but it would definitely help me to know his true intentions (especially in this particular case) and I did try to reach out to the charity, but I didn't get a response yet.

No worries. I could've done it myself, but I don't think that scrapping is a good solution. AFAIK, Facebook doesn't show all the usernames. It would've just displayed something like:
"User 1"
"User 2"

You could try to search any link between his profile and the project by writing his name and the project's name on the search box. Then filter the search results to posts only. Hope it works.
Thanks for your suggestion, but that didn't work. I think it only works on the content of the posts.

Using inspect element won't work as I explained above and I know the permissions might be an issue, but I was hoping maybe I could retrieve such data directly from the page since anyone with a Facebook account can see them already? I couldn't find anything about that on the API documentation though...
I appreciate everyone's willingness to help. I guess I'll just have to wait for the organization's response.
