official DICE servers botted with fake players

this is an official dice server for operations maps. the server browser shows almost a full server, but when joining I'm greeted with all low level accounts with obviously fake names and all with ~200 ping.
none of them ever join the actual game, they just make the server appear full but none of them are real players. the server shows the waiting for players screen.
so why is DICE doing this on their own official servers?
