It depends on the group and how well it is moderated.

I live in an area where everything depends on Facebook. There are multiple FB groups for the town, the largest of which has 80k members. Not perfect, but not toxic. The same in other similar groups.

I am an admin of another with 30k members. It has a tight focus (exams and qualifications for home ed kids in the UK - GCSEs/IGCSEs mostly, but other things too), membership is only for parents of such kids (there are membership questions), the group is private, posts require approval, irrelevant comments get deleted, repeat offenders get kicked out. We do not have a lot of problems (some attempts at spam by tutors, but they get kicked out).
