I doubt it came from Ebay. Even when you request someone's contact info through Ebay they only give you the name, city, state and phone #. I just did this recently to get one of my buyer's phone#'s and I had to share my info with that person as well. The info I got and was sent to my buyer did not have my address on it.
I don't know why you are posting this again when your other thread was shut down.
I think that this is an issue that really matters to her and she wants feedback on it from others who are familiar with Ebay. Reposting it in a different way (not being accusatory, per se, but being inquisitive and wanting answers to her questions...I see no harm in that.
Additionally, I am curious, as I think we all should be. Ebay is a huge, monolithic company that has SO MUCH of our personal info and next to nothing in terms of customer service..those two facts leave me a little wary of Ebay as a whole. I have many questions I would like answers to but refrain from asking on Ebay because I dont want to cause any problems and I know that even if I did try to ask my question, I would have to search the labryinth that is Ebays website to find out who and what department I ought to contact
