Early in my Facebook years I had people on friends who I did not know. They usually lasted a day or 2. A few called me out by asking through others why I dropped them. They did not like the reply.

I look at it like this. If I have allowed you to be on my friends list, and you NEVER comment on a post, NEVER contact me just to say hello, etc... why bother having you on friends? So I have 18 friends on Facebook, all of whom I know in real life, and all of whom I interact with on almost a daily basis. I also have a completely fake profile so anybody asking to add me (they can't because of privacy settings) would just be phishing.

People are setting up shops on Facebook with slight variations of legitimate users, like for you they might set up PattMarr Inc, and then post fake ads to scam people. You wouldn't even know about it, but if they scam 1 person, they are ahead of the game. YOU get the angry email for the fraud, and they close their Facebook, open another, and do it again. So if someone wants to do that to my fake name, have at it. I am in no way connected to it.

Other than a tiny bit of fun for people who use Facebook in the spirit in which it is intended, it is an awful place.
