They could be "friends" then (like kreator with momojuro), lots of shill bidding occuring ... once I lost to "driver19880224" a cd on open auction, and "thrasher1101" relisted the very same cd again the day after, with an higher buy it now price ! He also says his name is "Chris" (chinese guy with that name ?).
I had to open a dispute for my selling too because he wasn't paying either, he started to pretend a 15$ discount (why does he buy a cd for an certain price when he actually doesn't want to pay that sum ?!), I refused so he said he didn't want the cd anymore, I replied ok, get lost ... but instead he paid the day before the escalation of the NPB dispute.
Then, when he received the cd he started to complain that it's not mint, it has 'euphotic scratches' (whatever it means !) and wanted a 15$ refund (again) or else he would leave negative (feedback extortion ftw !) and open a paypal dispute.
I obviously replied negatively so he opened the dispute, writing that "the cd does not play" ! How come he was willing to keep a cd that "does not play" as long as I give him 15$ back ? Obviously it's all bullshits...
As i pointed out before, he is a seller too, but his account has been limited since a week (0 cds listed instead of the usual 1500 or more), and the funny thing is that he accuses me that I reported him

(for what ?! The truth is that he probably didn't pay his seller fees or he just got 3 NPB strikes ...)
This situation is a clear retaliation, the cd is fine, it plays 100% well, and anyway was listed as "Very Good", not "Like New" (it looked much better than my own copy btw !). Block this scumbag, no more words needed.
