Weird behaviour of "North Korea" (no disrespect) on global rank list

@admin North Korean coders from a similar place occupy consecutive ranks from 2nd onwards in the global rating list of codechef…I’ve never seen such a case with any other country…moreover North Korea has only a handful of coders (not even filling 1 page)…how can there be 8 “7 stars”?..please look into this matter…

There is nothing to look into.
