What to do with the ethically challenged?

I’ve been thinking about ethics a lot today.  What do you do when someone treats you in an unethical manner?  I tend to internalize it and move on.  Unfortunately, in this latest incident, I will have to be cordial and have some contact with the person.  I don’t want anyone to get the wrong idea, I’m not an overly sensitive person or anything, but I must admit, it does hurt when someone does something like this.  They play mind games and never had an interest in joining the organization, they already had a sponsor and joined through them or just wanted to play around.  I did nothing wrong, this person obviously has an issue with something and has no guts or verbal skills to tell me, the funniest part is, she said she wants to be a writer.  I wish I was at liberty to say who this person is, and let her account for her actions.  Perhaps I made a mistake and brought this information to the persons in charge of this organization.  I’m not sure that was the right thing to do, but at least it is off my chest and even if they think less of me for it, I will know that I stood up for myself.  I was surfing around a site I found and became really intrigued with character and what makes a good person.  There are “Six Pillars of Character: trustworthiness, respect, responsibility, fairness, caring and citizenship.”  The people who did me wrong have lost that in my eyes.   I don’t know what should be done with the ethically challenged, the only thing I do know is I will NOT let them shape my world view.  There are good people out there, and they want to support me and my business.
