Hi I'm Tariq 👋
I'm interested in infrastructure as code, serverless, dev ops, and all things cloud-related.
For programming,I usually work in Nodejs/Javacrript/Typescript.

If you're reading this then there is a good chance you are interested in building something similar or are simply a laymen who wants to really understand how this feature works(can't blame you, it's pretty cool :D). Just note, this analysis provides a high level overview of all the systems along with a bit of technical sprinkling. IT DOES NOT TELL YOU HOW TO BUILD IT, 

Because this analysis will also cater to the laymen, I will need to explain a few things that the developer may already know. skip this section if you're a seasoned ogar dev.so let's star:

1)The client-server  model 
the server is just a computer somehwre in the world that evryone connects to, as you may probably know,there is server out here in the world that every player connects to. the server sends data messages to the client
2) the client 
You can think of the client

Issue: Mischievous players joining through vpn,posting sensitive/inappropriate info in chat, and quickly leaving before a mod can successfully ban/kick them.

Solution: The server already maintains a log of all the ip addresses that connect to it, all we have to do is map the the player name with the ip address and log the time when the ip address is connected to the server. so somthing like: "Spectator59 192.168.2.1 22:14 June 13"

The mods can then inform noshu via dc on the in-game username of the troll, and he can then ban that specific ip adress. Of course, the troll could always get another vpn, but that requires effort, and I believe the effort required to setup a new vpn far outweighs the reward.

Improved solution(just thought about this): Mods gain the ability to ipban players that have already left the game x minutes ago.
