I think I would add that: if I would be posting stuff and then someone who was an acquaintance only - would hit up a conversation about my wedding photos from 5 years ago how he remembers all were great, or would go with conversation about tv show I just added on my profile.

I would not feel comfortable, to say the least, I would feel creeped out. I would start thinking what kind of MLM he joined or if he looks to borrow money as last resort as no one closer would lend him any.

If that would be my close friend that would be OK.
