What is this:

May I ask you why we can randomize seeds every 10 minutes? It is not bloody faucet, it is provably fair!
If I want to randomize it every second i should be allowed to do that!
People were simply changing the seeds and abusing the server. Hence we made this restriction. Even other big sites restrict to change the seeds only once in 5 minutes. If majority of the players find this restriction as an issue, we don't mind removing those instructions.
players also cannot change their
client seed. you're forcing players to use client seed you assign and just adding the nonce, meaning you already know the result of the roll. That's not how provably fair sould work.
You can click on the user seed box and update the user seed. I think you never tried to modify the user seed.
