No, a server is just listed there if someone registered the server at gametracker.
Yeah I know that. Almost everyone in current swat community knows how to register a server at gametracker and they do it everytime they get a new server (SAS,UTF,AST,ETS,UEO etc.). So, for new players it won't be problem to check all the servers since the list is being updated by current community. The problem could occur with new clans if they don't know about this...
And one can't see the current gamemode of the server via gametracker, so it's difficult to find a coop server
That's why I wrote that it will be hard to find coop servers. The good thing is most coop tactical servers have "tactical" or "pro" in their names so that's helpful in a way.
