Adding friends in classmates more than 5000 people?

Question

Classmates

I work in a furniture store and part-time engaged in website promotion. I registered in classmates as a regular user, but in order to add more friends you need to go to a higher level. That is, declare yourself (your page) as an advertisement or advertiser ... or something like that. Question: what needs to be done or where to go in order for the moderators of this site to give permission and not be banned as spam?
