Nope. There are three ways to get more followers: -put a profile picture of yourself if you're hot (and if you're willing to show your face/body to a bunch of strangers) -post/give funny and interesting questions/answers -get random followers because of random reasons
I don't post my picture on this site, so I don't get many followers. The ones that do follow me, I appreciate since they like what I have to say more than how I look. Only one person on this site has seen me... he isn't a creep thankfully.
I don't know, but I did notice a trend where females on this site have more male followers, and it seemed males had more female followers. Though my sample size was only 23 people so, perhaps it was coincedence.
I haven't tested the theory, but I'd imagine the number of followers is proportional to the amount of cleavage visible in profile pictures, and increases significantly if the relationship status is "single".
