Rule 10

Rule 10 refers to 'Rule 10' in the Super Smash Bros. Ultimate Ireland server, stating
"Rule 10, No Violent or Self-Harm Speech.

We strictly prohibit any form of violent or self-harm speech directed towards others. This includes advocating violence, using hateful language, violent abbreviations, or making threats. Any such speech will result in immediate action. Let's foster a respectful and welcoming environment for all members."
