Depending on your Python implementation? Because of DoS amplification? I don't see any necessary reason that a fake server is forced to "go offline" (aka crash or not being able to send out fake server infos anymore)
Mind quiz, what happens when:
- Spawning a fake server, collecting the IP of every user requesting a "getstatus" (aka a player refreshes all servers)
- sending then constantly for like a minute fake getstatus-responses with the spoofed IP's of all the other servers to the client who just reqested a getstatus from you
