Hi Bob, and all
I maintain a few Facebook groups and it's something I deal with frequently. As Emily
and Alan suggested, I would set up your group so that people have to answer three
questions before they are approved. It's definitely more of a captcha-type,
prove-you're-not-a-bot exercise, but it's good. If they don't answer the
questions, I usually don't let them in. Even when folks do answer the questions,
I'll still check their profile to make sure they have a certain number of friends
(mutual friends are even better), and a good number of "real" posts with
comments on them, to see if they're real people (so not just cover photo and profile
photo). Even then I'm a little suspicious if it's not someone local. It's so
frustrating that we have to be so diligent about this stuff, but we have to be careful.
Even people who are "legitimate," "real" people can be problematic
sometimes (I had that issue with one of my groups recently).
In terms of having friends, I don't agree that more than 1,000 means they're
selling something. I have more than 1,000 friends because i've lived in different
places and do different kinds of activities (ie: dancing, writing, cruising etc). Having
lots of friends doesn't necessarily mean they'll bombard your group with junk.
When you go to your Facebook group, look under the ...More dropdown and go to Edit
Settings. There should be an option to add questions there.
Good luck!
