It's a thread where people can know who you are talking to and show they aren't too chicken to post a pic. There is nothing sexual about it.
people on the g and o post a pic of nasser and get the comment "what a beast!"
alex23 post a pic on the y and get the comment "what a beast!"
no difference.
you dont see anyone on the v board, x board, z board, mma board, e board etc give a shit about peoples pic. because it adds nothing of value. if you cant bring it verbally then you cant bring it. period. then you should go look up facebook or something.
