I am *strongly* against this.
The unban requests are viewable, and can be responded to by any *one* moderator of the channel. If there is an abusive moderator in a channel, whispering the broadcaster is one of the very few ways to contact them directly and lodging a complaint that the abusive moderator cannot intercept and dismiss before any other moderator or the broadcaster even has a chance to view it.
Having a complaint box is useless, if the subject of the complaints can simply squelch any complaints, because they are the one who empties it.

The problem that is generated in that part is that many mods become tyrants, they have the trust of the streamer, but the streamer often does not see that their mods become abusive, worse when there are many viewers and the streamer does not follow up. . the Mod can harass with behaviors that pass under the radar of good conduct. abusing his power. and poisoned the user experience, the mod is there to impart the correct use of the chat with its tools, not to rule if its judgment is total and impartial from start to finish. If the viewer starts harassing the streamer or any other user in the DMs, I totally find the total ban fair. but right off the bat it is not correct, it is the complete opposite of being fair. there must be a verifiable behavior, and not react to an event that has not yet occurred. twitch is pretty full of toxic people. but the righteous can't pay for the sinners, just because of a misunderstood context, or to save you trouble, which is what certain types of moderators often do when they find themselves outmatched, or when they need to show that they are making use of their role and who are active in that task so as not to lose their mod position. And last but not least, there are channels that don't mind losing 1 or 2 viewers unfairly or misunderstood. Just because the chat has the dynamics of banning someone, it's like a Roman circus. and we all know it, let's not pretend to be blind. They do it when they see that 1 does not matter, if I have more than 1000 viewers, it has happened to me, and I have seen it.

100 % agreed!

I totally agree with this!

I also agree with this, so much

Very much agree with this. Should be directed through the proper unban request channel and all contact should be blocked otherwise.
