Block accounts coming from Minecraft Account Generator

Hello, everyone.

I'm writing this comment, to propose a Minecraft anti Account Generator integrated in the "server.properties" file as the "online-mode=false" function.

Why is that?
Some users of its services use them for dishonest purposes (for example: anti-Semitic remarks, insults, cheating, harassing someone, etc.).

I grant you, there are ways (plugin) to prevent this kind of things but it forces the servers to provide a lot of protections that result in :
Dropping server performance
Block access to VPN users and cloud gaming platforms
Etc...

It's very hard to have all the IPs of a player with Dynamic IPs, which are sometimes shared with other players with Dynamic IPs.

It's very hard to have a complete list of his accounts for blacklist and not talk about them anymore. For the example write "Minecraft anti Account Generator" in google.

Please forgive me for the length of the message but I wanted to argue.

Best regards.
