The question is what can we do about it. That's kinda part of prison: you need money, and when you are just lazy and don't want to earn it, you just beg for it, I know it can bother people but like 75% of the people does and will do on the prison. I feel this shouldn't be put as rule for a reason I've stated above.
It will sadly not become a rule. It's apart of prison, and there isn't necessarily a way for us to reduce it. It would also be a very unfair punishment indeed. The way to decrease it is by either telling them to tone it down a bit, in a polite way, or by running the /ignore command if needed. Otherwise, very sorry
