There's no coordinated attack in progress against the Turkish community--that's all in your head, sorry to say.  Nor is this some sort of case of racism/nationalism/whatever on the part of DarkStar_ or Chipmixer or anyone else.  The campaign is extremely competitive and there aren't that many slots.

Blue-blooded native English speakers get turned down from Chipmixer all the time.  It doesn't have anything to do with where you're from, because I can almost guarantee you DarkStar_ doesn't even know in most cases.  It all has to do with how good your post quality is and a secondary consideration is how trusted on the forum you are (as I understand it). 

This thread reeks of jealousy and playing the race card, even though there isn't exactly a specific race involved that I know of.
