Actually I take back saying it was Boltster, I just assumed he would be more likely to spend money on doing something like this.
But actually, I think this is more of a light hearted joke because it players on the whole "grammar" thing from that one drama. I don't get malicious vibes from this one... it just doesn't seem like Boltster's style imo.
Also unless someone was just being thorough, the email account they used for the mock YouTube channel is registered to an under 18 person because YouTube shows the child silhouette in the channel icon. Clever touch or slip up?
Anyway I think its just a playful joke taking advantage of the $5 key thing.
