Team members are meant to represent the school.. And I don't think felons are great representatives. (COMING FROM SOMEBODY WHO LOOOVES HER FELON CHAR).
Just because someone does not have a KNOWN record does not make them a great representative. There's people currently on teams who have committed crimes and have not gotten caught and still act like that great team member you know and love, A known felony does not change a thing about how a character acts. If the character changes and moves past that gang life they deserve to continue to develop their character into factions rather then throwing them out and starting a new one. Being a gangrper should not stop you from continuing to develop your character into a different light AND WE AS A ROLEPLAY COMMUNITY should be encouraging people to do that as it makes roleplay for everyone more interesting.
