After a long and emotional discussion in the eveonline forums the game design department decided in a meeting that their will remove the kills statistics for all wormhole systems in the eve online maps api. This change went live on the 3. June 2014
2.5 years ago CCP already removed the Jumps data from the api for all wormhole. Why nobody removed the kills at the same time is unknown. Anyway … Unknown space is meant to be unknown and since there is now ingame equivalent present in the game to gather npc kills statistics for wormhole systems I can understand the decision.
I know that other may have a different viewpoint on this but that’s the decision from CCP and we’ve to live with it.
