There should be an option where u can star a server and it will always be on top and u can also do this that servers in which no one joined in last 7 days it will be moved to a another section called "dead servers" where u can go and then join them.

Pls consider adding this it will help a lot.

I don't think ClassiCube.net has the ability to know about the specific server that a player joins for the purposes of tracking visit statistics, save for the web client. On the standalone client, I believe a request is made to the following endpoint: http://www.classicube.net/api/servers

Once the server list sends all the IP addresses of the servers in JSON format, as well as your mppasses, there isn't any further need to make another request to any of the server list's other endpoints. This would mean that the server list doesn't know which server a player joined, only that a player requested the current list of servers. To clarify, an mppass is your "ticket" to join a multiplayer server that's generated by the server list.

Now, the web client is a bit different, and in this case, the specific server that a player joins can be tracked, through a server play URL: http://www.classicube.net/server/play/f56580cc7df60ae70ac95dcb025f4690/

This is the server link for Panda Anarchy, and while server visits could definitely be tracked through this method, I wouldn't say it's ideal enough. You wouldn't want a server to be marked as "dead" just because its entire playerbase happens to be too cool for the web client, would you?
