Most SM sites have models so the girls can be discovered. These are the BEST sites.
Other SM sites just have models to judge the pretty/hot ones. These SM sites are usually hosted on facebook and myspace. Girls on these sites just want compliments, attention and to be discovered. But be serious, no photographer wants to do a shoot with some slut with her bleach blonde hair up in a messy bun and pounds of makeup on. These girls are not fit for being models.
Real site models are naturally gorgeous girls who are truly passionate about SMing. If a great model plays her cards right, someone from a magazine might see her photos and give her the big break she deserves.
Emos love SMing. It gives the girls a chance to see whos the best scene queen of the site. They want attention and sympathy for the 700 photos of their cuts. The only boys you will ever see on a SM site are most likely emos. Don't bother; they do NOT want to date you. Being hot boys that SM, they get a lot of attention from desperate girls. Leave them alone.
Watch out for X rated SM sites, their models post nude pictures. These are usually wannabe pornstars who just want to see boys drool over them.
So some sites are good, others are bad. Some girls are good, others are bad. It's easy to tell which is which, but good luck anyway.
