it might be time to codify rules about the masterserver list access for server admins and how violations are handled to prevent any misunderstandings.

The only old (and i think by now outdated) information that is written down is:

Unvanquished is currently a small community. Please don't aim to create a server in order to only compete for players.

Division of players will disallow larger matches.

What is and what is not expected from server admins?

I think what happens on a server should be free to the owner to decide.

The servername is displayed to all players independent if they join the server or not so there should be some rules for that.

Like Prohibiting:

• anything oblivious illegal or pornographic
• oblivious insults
• obstruction of other servers in the list (that other names cant be read)
• making the serverlist look buggy
• impersonating other servers (exact copies. similar name patterns or colors should not be enough)
• using other playernames or clantags without consent ( common names need case by case handling )

Breaking of rules should be handled by contacting admins and warning them. If they don't comply or react after reasonable time, depending on how serve it is and if repeated offenses, the server gets banned. There should be some kind of process to have this transparent to prevent any hidden abuse.

https://master.unvanquished.net/ignore.txt is already a good start. Maybe a entry in the infrastructure tracker about circumstances for every ban would be good.

There is also a need for a process how a appeal and unban can happen or other less strong measures compared to bans.
