I was talking about posts on their page.

Can't believe anyone would change a privacy setting to get in a group...
And I actually like that you try to reunite cars & parts/paperwork.
But people shouldn't give FB access to anyone they haven't personally met.. period.
That's just basic" personal security"... it's to easy to scrub FB info.
(Home address,education, workplace, e-mail, phone#, cell#, birth date, mothers maiden, kids & pets names, etc..)
Most of the info needed to hack accounts, or open new ones... including bank.

You're not going to abuse it...
But there are thousands out there who will, and no one at home can "Verify" the difference.
