I thought you were to stop posting full title cards from NickNack onto this wiki, but you just posted one for "Teachers' Union", especially before the show's official social media accounts posted it along with the other ones! If I were an admin here, I would have you banned, but right now I am asking you to stop using NickNack please. I don't even know if the person in charge of it works for Nickelodeon (mostly the German unit).
Also, i'm sorry my earlier version of this post on your message wall told you to leave the wiki. I felt it was wrong, since you're not the real problem to me here.
It isn't illegal to upload the title cards so early. It's the exactly same with SpongeBob. Everybody waits that the German SpongePedia upload the title cards. I've never seen a user in the SpongeBob Wikia who said that he doesn't like the title card leaks.
Sorry, but the title cards aren't good. "Gesänhelt!" is no German word. "Ein Witz ken Schule" makes no sense. "Bildverbesserer" is the wrong translation. "Selfie verbessert" is the only correct title card. Sorry.
