2.10 Bribing - You're not allowed to bribe players to become other jobs. IE: /advert Change to cop so I can rob the bank and I will play you 50K or /say I will pay you 10k to change to thief and go rob that guy over there.
Quote from the rules that as far as I know applies to the message you took a screenshot of, but had the money part not been in there it wouldn't. I guess it doesn't really make sense for a criminal to attempt to get more cops in the city but I doubt this will go through since in the end it hardly changes anything.
