How do you become famous on this platform?

How do you become famous?
I’ve tried but never made me famous me and my friend has been on this platform for a few years now. We have made multiple groups and I think it’s because we don’t have alot to advertise with.

How do you get large amounts of robux?
What do you do to become famous?
Do you donate to other groups? (My plan)

Please reply, thank you!

I have heard about AFK games, but I tried one but didn’t get anyone because I am not rich.
