Exactly. Seems to be a trend of "This game is a knock-off of X" since Minecraft came out!
it's well-justified, i think, but just not well-informed in this case.
there are A LOT of minecraft clones. and the name "Blockland" is extremely suspect because it's rather generic and refers to blocks. obviously it's impossible for the accusation to be true for blockland, and a good bit ridiculous as well.
