Spammer?

I made this site (not sure if I can post here) where people can go and sign up to earn NX codes. I tried spamming over megaphone and not many people came. Is there a way that I could get more people?

Like a bot that joins rooms spams then joins another?

Site is legit btw no worries there!

well um u gotta ask a site admin

I mean to spam in game not on site.
