Forums are a strange place, in that members can know each other's views, writing style and life history intimately, but never know their real names or see their photo. How bizarre! Welcome to 21st century life. I'm not complaining. This is just an interesting observation. Although, it is understandable that members on an ex-Muslim forum will want more anonymity.
The question of security is much overblown to my mind. No Jihadist warrior gives a rat's tail about any of the spotty little chits here. There's much to be said for maintaining one's anonymity if a young member wants it hidden from his old man, or for employment reasons if you're a keyboard sex offender like some on this joint whose names it won't do to mention, but I'm pretty certain that Bin Laden has a better use of his time than monitoring this joint, grand though it is.
But if you want to seeing my face, you should come my YT channel. There my ugly mug on proud display for everyone to looking and pointing and laughing.
