It could just be the case of your friends deleting you due to your inactivity?
Ever since I started it due to a writer friend wanting to play little games with me on it, I always thought that it had potential, but people just didn't use it.
It should have been like on here, friends and family having frequent conversations, but all it was, was vague single posts and pictures of food. I had friends from high school and family on there, but checking frequently made me feel lonely, like nobody gave a shit about me, so I ranted and made dark jokes, until I fell out with my Dad and put it on ice, then reinstalled, but stopped bothering with it when we made up months later.
I'm still on it, but I just check every once in a while. The writer friend is still there but she doesn't write anymore, just posts about her shitty co-workers and my Dad and my Dads wife's son lost about their motorcycle escapades. Everything else is a viral video or an ad, and there are lots of them.
It's shit.
