At first, I am in disbelief about k.org and b.org - I figured KORG would have acquired the former and some Star Trek fan (or Paramount themselves) would have acquired the latter. But then I realized that the holders of these domains were probably asking too much and while there's no infringing content being hosted, the owners of these marks don't care.
If you're planning on acquiring one of these and hosting anything related to someone else's "IP," be ready for legal harassment.
