The first thing I do before replying to a post is check the posters profile, to get some idea of who I am talking to, and who I might consider being friends with. Initial restrictions may only serve to put genuinely interested girls off. What’s the point, they will think, if I can’t do anything?
As Grace pointed out in another post – a virtually blank profile may be genuine or it may be an indication of a potential troll. Everyone is encouraged to fill out their profile so restricting access to it defeats the purpose of it.
