Ok so this is a FB question?

On Facebook I know these very hot but deep down inside I know they're are all fake. Girls. I write then and stuff. It's obvious they're fake. They put up fake pics. And I was just wondering how they manage to write me when it doesn't say on mobile or active now? They just write? Who could they really be?

Now I'm not a tech expert. But it almost sounds like they are messaging without the setting to show what their messaging from, could appear offline or using some 3rd party app to message (text messages could possibly work too)

They are those people who want to enjoy and want to share everything which can't be possible with their personal profile. It may be that they're those people who are advertising products in facebook. It may be.
