So I wrote this response back to her:
Hi,
Thank you for deleting Jess's account and removing some of the threads.
What you don't seem to get - and maybe I didn't explain it well enough, so if that's the case, I apologize - is that this Jess is the same person as LuckyMe, who had a big problem with plagiarism here back in 2006. A friend of mine had to physically mail a packet of proof from Canada to Jonathan in England to get him to remove the threads with plagiarized stories then, so I really appreciate you being more helpful.
I feel strongly that the users on this site deserve the truth about this girl, Tanja (a.k.a. LuckyMe, a.k.a. Jess). They have been duped by her. Some of them think they are her friends; others have enjoyed reading what they believed to be her stories. Some of them seem to be aware that Jess was banned for plagiarism, but none of this has been confirmed by anyone in authority on your website. I think you need to post an official statement, warning your users about this thief, not only to make an example out of a known plagiarizer, but to set the record straight on behalf of all the people Tanja has cheated by stealing stories and claiming them as her own.
You already have a platform to do this in the "PLEASE READ" thread you have stickied. It would be very easy for you to simply add another post to that thread, explaining what happened with LuckyMe and Jess. That way, your members can be on the lookout for future incidences of plagiarism by her or other members. Also, it will keep the victims of this plagiarism - the authors whose work was stolen - from feeling the need to come and add their own two cents. They are doing this because if they don't, there is no one to tell the truth. You can be that voice, and do it the way you'd like, calmly and professionally .
Thanks so much for your support and cooperation!
