I love Facebook for the Buy Nothing groups…..I have seen some incredible stuff given away.
There is also a site for local info.
Not all is bad.
.
Not even aware of those and not interested...however whatever floats your boat as is said.
Just remember this: You use their product (Facebook) at no up-front cost to you ... if you aren’t paying for it, YOU are the product. EVERYTHING you upload/post/identify with is THEIRS to use as they see fit - EVERYTHING.
Addendum to my previous reply; the ONLY way around it is to set up a COMPLETELY fake identity and NEVER post anything personal. EVER.
