Considering that he has already gotten over 150 reviews for pictures that he has already sent (and assumably has recieved money for), I'd say this is serious. My German is not good enough, but can someone here please send Ebay an e-mail saying that these photos are copyrighted and appear to have been stolen from Airliners.net, and we want a full accounting of all sales made by this guy. In addition, we recommend that in order to avoid Ebay's name being dragged into the mud, that "cridorini" be banned from selling on Ebay.
If you are an Ebay member, you can post a comment of your own in the meantime, saying that these pictures are stolen, and pointing a link to A-net if anyone cares to verify.
