Why is my game code the only one thats been removed?

[xsixonethirdx]

So I had posted a Steam game key on ebay to try and sell it and make some extra money. Next day I log on to check the status and I get a message saying that my listing has been removed because of "copyright violations" yet every other game key that I had seen originally was still up and being bidded on. So I'm kinda curious, has this happened to anybody else? If so, what did you do?

Someone reported your listing. You do not know how many others have been removed prior to yours and you do not know how many others will also be removed if they are reported.

If you feel the other listings are also in violation of the same policy, feel free to report as many as you like.
