Question 1: How does player reputation affect you?
It doesn't. I have to see it for myself if it is to affect me. If there is a reputation, I might look for it whereas otherwise I either wouldn't or would discover it for myself. However, if I know about some kind of behavior of a person, that I've seen myself on several occasions, that 'reputation' will certainly affect me in the future.
Question 2: Are you influenced by how the RP community looks at you?
No. I know that people don't like me, so I have nothing to lose. People don't like me in real life either, for various reasons, once they get to know me. My negative sides heavily shadows my positive ones. If I let how people look at me influence me, then I wouldn't be able to do anything at all.
Question 3: How important is learning from your reputation?
I'm impulsive, brutally honest, a perfectionist, jealous, and manipulative. They're difficult traits to just 'change' because people don't like them. But, I'm very aware of my faults, and I try to control them, so there isn't much to learn from a reputation that I already know about.
