I think only from android you can find your server, using the google app netstat.

The top of the server managers, you just meet them sooner or later when you are playing for a long time, you 're active, support friends, watching who else is supporting and test them.
If they have the button of add a friend, they are in the same server and you can add them without fb.
Then, you see their opponents, in which position they finished last season and if the game promoted them or they 're repeating the same lv.

Sometimes you meet them in the forum or some fb groups, usually locals as the game many times put teams from the same country in 2 or 3 same servers.
At least the very old managers.
