Hello, when we ban someone from a server, there are logins with side accounts. There is an IP ban to prevent this, but it doesn't have much of a function. Most players open a VPN and log in with their other account.

I think extra security is needed to prevent this. When we ban a person from the server, serial ban should be possible. This could be a motherboard ban. I think this is something necessary. Players can no longer be blocked by IP address.

This suggestion may have been made before, I haven't checked.
You can criticize my suggestion, but this is a suggestion, do not take it too seriously.

There is a way to implement anti-VPN systems, @DriftingDion had something like that implemented for his LCS Cruise Servers. However, last time I was in contact was around a year ago and IDK if the system still exists.
