"Interaction" must be heavily controlled by DSP in a way he can figure out with zero effort and must only be to talk about him or to help him playing the game.
Talking about the NFL getting excited for tomorrow? Banned for derailing chat.
Talking about Clash of Champions (WWE) tomorrow? Banned for derailing chat.
Talking about Judgment? Too late dood, we already played it.
Talking about literally anything other than DSP; STOP DERAILING CHAT!
This is maybe the "worst" example I can think of for how petty it was:
From DSPGaming (sorry Youtube search-fu couldn't find a non DSPGaming video).
A guy cheered something about DSP playing online or asking how online play was after DSP just beat the single player campaign of Smash Brothers Ultimate.
DSP's response? "Yes Derek, I got your cheer but it's kind inappropriate to talk about online play when we're watching the credits of the single player, no?"
Yes, DSP chastised a fan for talking about a different mode of the same game he was currently playing. After he had just finished it. "We're watching the credits!"
