Adding to a sentense like
'Not reading server rules and acting contrary to role play rules can get you banned from this server sooner than you want.'
to the login would solve a lot of noobs misbehaving. You dont actually have to ban peopel more, just threaten it at the login.
Also, add something like a 'mini quest' to keep newcomers busy for the beginning of the game, like making a small ship with mining, then using a certain traderun, then fixing your rep to go to a certain place where u can get your first VHF for a low price (thus making the whole thing worthwhile). The 'storyline' or 'what you are expected to do and what you will gain' can be told by commodities like the 'history of serious'. Kind of like a tutorial for disco that teaches you the essentials and gets you interested in RPing as well. I saw something like that on a vanguard server, worked pretty well. Something like the oracle quest, except that it should be very easy and intended for newcomers.
About the 'abuse of power':
When you start playing on disco, you feel that there are 2 types of 'higher-ups' or 'long term people' here.
1: people that are polite and explain you the rules when u violate them and give u useful information on how to fit in better. They treat people with respect so get respect in return.
2: people that have learned the rules and use them to be jack-asses and get their way. They
-are rude and insulting in the worst way without using bad words and then report you when you talk back
-tell oyu they dont want 'your type' on the server, or arbitrarrily decide that your kind of RP doesnt have the right to exist, so they will do their best to get rid of you by exploiting every little rule they find
-try to tell you you are acting oorp while being more oorp than you
-enjoy being disrespectful because ur a noob and they are all powerful since they are here longer
Some people seem to confuse 'being on disco longer' with 'being more mature', and should check if they fall in category 2.
