How would you go about making an auto rank bot?

Alright, so this is a complex question. I'm trying to make an auto rank bot, but ever since Roblox's cookie update I've been unable to find any substantial tutorials on how to go about doing this: devforum.roblox.com/t/ip-changes-invalidate-cookie/1700515 Does anyone have any tips on how to do this?

https://github.com/noblox/noblox.js/issues/545 This is the guide on how to fix it, but let me be honest. My knowledge of VPS and SSH is very limited, so it's extremely hard for me to understand this tutorial.
