To put mine simply.
My first username was XLRaMpAgExX, and I can't remember how I came up with that.
I grew out of the name, to say the least, I just hated the way it looked, so I bought a new account.
At the time I was thinking of making an animation and/or gaming channel with my friend Dan, the original names for the channel were Laughing Cactus Media, Cooked Steak Gaming and Porkchop Media... I know, really bad names.
But then Dan stepped in and said "What would you call a block if it was strangely untextured or glitched?" I answered "Corrupted", hence, CorruptedBlock.
