In Character reglas shouldn't be thought of like faction rules. Good roleplay can stem from characters breaching or bending the reglas to suit their own interests.
Mainline reglas can also be a lot like the Mexican Mafia's reglas. There are 'hard' reglas and 'soft' reglas. Some might be broken routinely and are just there for show (soft reglas), and some might be taken rather seriously and really do have punishments attached (hard reglas). I'm not going to list which is which. It usually depends on the mindset of the shotcaller(s) at any given time, and how they choose to interpret and apply the reglas. This is something for faction members with leadership characters to consider also. Don't treat the reglas as gospel, it might be practical to ignore the application of some.
Keep this in mind when you roleplay. What can your character get away with? How does it benefit him? To repeat, the reglas are not faction rules. They're completely In Character. Do with that information what you will.
