Same as twitter really, think about it for a second (now I dont condone this type of thing)... A guy would rather accept a request by a hot girl profile pic than he would some guy contacting him to be friends, yes? Women are seen to be less threatening than men and generally men go gaga over hot girls so imho it is all a marketing approach/angle to get them to see whatever they are promoting. Same as why dating sites generally show more pictures of females then men. (not all do, and the smart ones use multiple landers for affiliates to promote to genders) If a guy goes to a dating site and see's more men then women he might consider not signing up and going somewhere else. Just my 2 cents And I am sure by now many people can distinguish between a real profile pic and a staged model pic... and if u did get contacted by a real model then count yourself lucky man... lol
Girls make male Facebook accounts because some people think women don't exist on the Internet. Guys make female Facebook accounts because sex sells.
