Ok, now I get what you mean. I'm assuming they implemented this feature so no one could rep boost or shit like that. I think this could be changed to like as many posts as you want, however, you can only like particular peoples posts 1-2 times a day. +1
I'm not suggesting any rules for the server, however, I think it'd be useful if there was a thread or sub forum displaying all the rules for the in-game server.
