He tried to get in touch with many gurls (mistake on purpose), but since some of them were pretty active on his first account and he could not talk to others from that account, he made the second one. And so on :))
Also, I have seen people making second accounts for anonymity, like getting into political fights, but without letting this messing up with their friendships. I guess there are a lot of reasons why people who are socially active on Facebook will have many accounts, I needed my FB account for an university group where announces were posted, homeworks, projects and stuff like that.
So if he is talking to 5 hot chicks at the same time, and if each of those hot chicks has five accounts to talk with 5 hot guys, and so on, the numbers could start to make sense.
You got the point :))
