As the title says, just edit the rules message in the #info channel of the ManaCube Discord to specify what constitutes bad voice chat behavior. These violations seem to be very common, so doing something like this might serve to at least mitigate the problem.
Here are the prohibited behaviors, as I understand them to be from the very wisely implemented #punishments channel:
- Using a voice changer
- Amplifying your volume to earrapey levels
- Playing earrape through Rythm
- Hate speech, probably constituting disparaging remarks about race, religion, sexual orientation, etc.
- General toxicity
