mark123,
i hate getting mixed up in messy situation (because they find me anyway lol!), but from the looks of things, you essentially took this rude individual's money (i've only gathered this from the way you didn't deny it). you don't really have a defense. this person was probably unfair with his expectations, but by taking her money all that you've done is further hurt us writers' reputations. just like ukrainians and others have done in the past. you stole, and should return the money to her.
from my experiences as a writer for phd-thesis, we really have no place dubbing client's behavior "unethical", because we're just as unethical as them... if not worse. once our (questionable) moral compass starts clouding our judgment, we lose sight of our initial goal: to write essays in exchange for money.
and finally, why would you mention that you would notify her school? for someone with a "10 year squeaky clean record of excellence", that's simply beneath you, and once again, hurts all writers' causes.
this website's main purpose is to warn both writers and their clients of the dangers, and to try to give them some insight into who to avoid and why. argumentative defenses are unnecessary. if champs83 feels the situation is resolved, and makes it known here, it will be an endorsement for you. you should've approached the situation like that.
either way, i wish both of you the best of luck and i hope this situation gets resolved ASAP, and lessons are learned by both sides.
Just as a follow up; I've looked into this myself (I'm organizing a collection of writers in Eastern Canada), and it appears that this scammer continues to function freely with no resistance at all. Typing in her name online gives you a slew of results, none positive.
Every 7 days she makes posts on craigslist as a tutor for English-based exams and separate ones to correct and write essays, but she cycles with different email addresses (interesting???) 3 different ones in all; so in any given months, there's never the exact same posting. When I once inquired into her services, she was polite by email and even insisted on speaking on the phone. But once the financials were mentioned, and I told her I wouldn't pay full in advance without references (which she wouldn't provide - yet advertised having 10 years worth of references), she got rude, hung up on me and won't return my emails.
Be aware!
