Pontiac Engine Design and Theory is one of the better ones. The classified pages are fun to look at but they don’t police scammers as well as a site like this one does.

I'm in several of them but with a few exceptions, most are horrible with clowns and imbeciles everywhere you look so none are worth mentioning. I mention to many users in these groups about PY Forums because you can learn from many here. I hope that helps people trying to get into the hobby.
