I would hope if Badspot could reply to this but I spoke to Shedletsky on a website (not roblox, its called turntable, I know it was him for a fact though due his twitter being linked on the website) and I asked him about if he had heard of Blockland and he replies this:
I am a bit skeptical whether or not he is lying because he said "them" although Badspot could have came with Rotondo or Kompressor
