Well, first off.. Welcome to TWK
Secondly. About the skyblock. We've been having some MAJOR problems and issues with the world designated to skyblock which allow people in the skyblock to get items, weapons, materials and various other things that should DEFINITELY not be available in skyblock, this allowed people to rapidly level MCMMO Skills to the point that it ruined the game for others and for that reason we removed access to the skyblock world to most users. as we've not found a fix yet (as far as I know) access will most likely continue to be restricted (I may be able to sort something out.. MAYBE).
Sorry for the inconvenience
