Thanks to the massive amount of friendry bumping the old ROBLOX threads here, I've been seeing a lot of people call each other "ROBLOXians" or "Blocklanders". You people are taking it as if the games are like loving ethnicities. They're two games, and there are four different people who refer to this game: People who play Blockland, people who play ROBLOX, people who play both and people who play neither.
tl;dr: Stop calling each other ROBLOXian/Blocklander. It's loving gay.
