Scraping FB group links?

Hi. I'm trying to join the biggest facebook groups that match my search criteria. I've been doing it manually for now: I enter my keywords in facebook and scroll down forever and join the biggest groups.

Is there a way of automating this?
Thanks in advance.

Just use something like Massplanner. Its cheap.

If you want active big grups than you need to do it manually. If you use software than you can find big groups 20k 30k but most of them will not be active.
