I'm kind of in support of this, but i think what the others said above applies as well.
The Demote system is decent but could be better, especially since theres so much conflicting info about who can demote and for what. I've also brought up the voting system before in some of my larger hangout groups, and almost everyone ive ever asked doesnt even vote when the votes come up since it can be buggy and also easily missed.
I think adding something like being a regular to access the job wouldnt hurt anyone, while we dont struggle a ton with MRDA, I have seen how frequently new players abuse or misunderstand the PD jobs even when their intentions are the most pure. This morning alone i've helped 4 new players to understand their PD jobs better, especially considering how easily new players get lost when it comes to "illegal weapons vs class weapons".
Adding some kind of time gate would in my opinion be beneficial both for regular members of the community and new players. Starting off on the server getting a warn for something silly isnt fun just as much as being arrested or killed isnt fun.
But idk thats just my thoughts. if you havent already id put this in the suggestions end of the forums!
