The basic idea of this program would be to add rewards for players that mass promote the server.
This could be made in multiple ways, but Ill leave my ideas here.

1. Media Rank:

Media rank is nothing new to the minecraft servers comunity and can be seen in a lot of servers, this rank would allow players to use Replay Mod, and give them the same perks as supporter.

2. Paying system:

Another way it could be done, and it has been seen more recently, is a paying program, the way it usually works is by giving players in game money for their contributions on the promotion of the server
Example:
I post a video on ccnet advertising the server, if its a TikTok, YT Shorts or other types of short form video, I would get 0,5$ in game per view, meaning 1 Million views = 500,000$ in game

And If it was a long form video, it could be 1,5$ per view


Of course these values were made up, and a more consistent formula could be used to define the reward system, but it would really help out with the server promotion and player counts, but these things have been proven to work, and we see that the biggest servers in the world are like that just because of these social media advertisings, and I do not think it would hurt the ccnet economy if players that can showcase the server to over a million people would get 500k.
