Server Sided VS Client Sided

No he meant server sided. Client sided is when you can control something that is on your computer. Therefore the hack would work since you are hacking something that you have access to. Server sided is when the server itself is active, analyzing everything that is done. To apply a hack to a server sided bit of info, you will need to hack the server itself and have access to it. I hope that even remotely made sense. Some hacks also have two sides to them. A server side and a client side. Where the client side is what you see and the server side is the reality (GP hacks for example).

i hear an argument brewing

Lmao *Walk away*

follows o.o

Regardless of whatever is server-sided, it must call upon client-side data at some point. Data is only partially server-side at most. It's being executed on your computer, and is therefore insecure. Server-side does not mean unhackable.
