Allegedly...
Ko9 couldn't deal with, or didn't want to deal with, the stresses of the attacks/hackings/dupes. Si Force planned on trying to carry the torch, but realized IRL stuff would be compromised too much, so he had to step down. The project was dead from there, but there were small rumors that the players files might be transferred to RuneRebels. From there, it sounded like Ko9 would not release the files to Si Force for the transfer, so now the project and player data is dead from ProjectRS06.
