Case hacking?

i don't know if this is against the rules. but why isn't there any case hacks. i mean the keys are probably saved on a database so you can't really duplicate or something(or it's just extremely hard) .
but the case opening seems like its a client side(generated) thing. so you would still have to buy keys but the rewards would be big

afaik cases pretty much have predetermined items in them

Last time I checked the inventory is server sided and the cases have server-sided code with what item is in it.
