Why hasn't Nick taken down all those "Return of the Revenge of Dr. Blowhole" episodes and clips on Youtube and fanpop?

My best guess is that they figure with it being such a big episode with Alex and Blowhole and all of those songs, it's gonna be on the web one way au another. Actually, now that wewe mention it, I think they might have even planned it out from the beginning. When that Comic Con video of Dr. B's Power Ballad was ilitumwa months before the special aired, it was never removed, either.

It takes a while for them to catch up, I suppose. When the onyesha was starting out, episodes could be found on YouTube for months at a time. I don't believe there is any special reason why the Blowhole special is lingering around longer than most.

My guess is...... is that Nick is stupid ;3

I would think that if they don't air the episode as much, it would seem a bit disrespectful for them to remove the only chanzo where a PoM shabiki could watch PoM. They'd rather focus their energy on removing SB episodes since it actually has a negative financial impact on them. For PoM, they wouldn't lose that much money, with au without the PoM episodes.

If PoM would air more, then Nick will be a bit zaidi strict on copyright.
