Part of Blockland's terms and conditions states that Badspot owns anything that is created in or for the game. So there is that. However, it's also generally accepted in this community that you're a gigantic jerk if you try to take credit for a build someone else made. Being the primary operator of Boss Battles, I have the power to ban as many jerks as I want.
Regardless, this topic is resolved because I unbanned him after his dubious apology.
