It sadly also applies to people who have been on this server for months. Sure, your RP is enjoyable and all, but who are you to put yourself above everyone else?
Depends on your definition. I call myself a good roleplayer simply because I divide people in good and bad roleplayers. Bad roleplayers are people who metagame and/or powergame, or can't talk in full sentences. Everyone else is a "good" roleplayer by default.
