Totally unethical in my opinion. I expressed this view point once on the topic and then turned around and found my account banned from the site.
Far as I'm concerned that in itself speaks volumes about the person in question.

What really blows my mind? Why would she have kept the codes? Youve sold them....what need do you have for them?

To use the car analogy, I think its like selling a car and keeping a set of keys. For what? In case you see it on the street some time you can just hop in?

unethical, at the very least.

I stopped useing tradespot after the original owner sold it.
Yes thats scamming.
I don't use my isp email for.... anything let alone for a site run by a woman like that.
From all i've heard she's a phycho, a scammer, and more. She doctors posts sets rules so that she priofits. Only her and her cronies are allowed to sell certain things, etc.

ehh ive got competition now! !!!!

*points above* that is my opinion.

It's a total scam because she didn't state what she was really doing. Now, if she had said she was selling just the codes, without the goodies, then that I would be ok with. Even though it's unethical to use the codes, at least she would have been stating the truth.

But she didn't...so

Lynn used to be a friend of mine i learned the hard way she wasnt much of a friend....she always went after things i had or wanted i know things about her that yes i could post but i wont.......adam knows what i know about her and thats all im going to say
being one of her bitches isnt/wasnt a fun job and in the end i regret it
the soulstone thing was wrong and i think she knows it

*sigh* personally, how can people of such low class, low enough to scam that is, still have such a huge rep and everyone thinks they're saints.

I would say it isn't legit for her to use the codes after she had sold them to someone else.

one thing ive never scammed and i dont think im a saint(hell I was never well known" and i feel very badly for having been apart or been involved with the ppl that i once was.
what kills me are these sellers that pull scams and get away with it because of who they are and sellers who sell items they dont have meaning they go buy it after they have sold it and make customers wait sometimes as long as a week
if the code was sold it was sold you have no right to it anyone and everyone but the one who did it would agree
the buying/sell world of uo is full of scams and drama i could write a graphic novel with what i know.....and i bet it would be pretty darn good
