First off, this is not required at all since you will get decent amount of traffic to your server with or without promoting it.
However if you still want to get one of the top 6 ad spots follow the steps bellow or join our discord and check the #announcements channel.
[Profile] and [Server] badges are permanent. They can be found at the Candy shop. (Shows up after registration.)
Badges are useful only if you plan to stick around. Perfect for hardcore server administrators/owners.
it’s pointless to own a badge if you are just casually releasing a server for a month or two.
May the gods be with you!
