Spamming hi5..Tips and tricks anyone?

So i'm planning to spam the shit out of hi5.I have h5 robot now,don't know if it works but what i'm interested is how can you get away with it?And what form of spam?Like just friend request than mail?Is it any other way?I'm a total noob with hi5,i don't like these kind of sites but i need some users for one of my sites.If i spam 120 000 accounts i'm thinking at least 1000 will be my users (since my site isn't for shitbrainers like hi5 users).Oh,yeah,thanks for the tips
