So called "Left" still censoring and blocking pro DPRK material

Tried to post some anti south Korean puppet stuff on Indymedia and they hide the posts ie banned them, Once they just even totally deleted stuff. Why does Indymedia which proclaims itself anti capitalist and anti corporate block pro DPRK or even anti SK postings.

 Also have written a letter to the Morning Star which so far has not been published,(still waiting maybe there is a chance they wikk publish it )Why do the so called Left try to censor pro DPRK stuff
