I will say this. It's a possibility that they're blocking it on certain YouTube channels. The more notable high subscriber ones. Because my superchat was done on Ethan Van Schiver's channel. He has a low sub count and could be flying under the radar. Sidescrollers i would think has a higher sub count and and they're known amongst youtube as counter culture against video game journalists.

I only found out it wasn't the word Trump because I removed Trump and the superchat still didn't go through. I continued testing by removing other words and it continued to payment processing screen when I removed 'evil'.
