I don't block a lot of people, but if you do any of these, you're blocked
- Discrimination of any kind (racism, homophobia, transphobia, etc.)
- Harassment (bullying, sexual harassment, stalking, threats)
- Repeated behavior that doesn't stop when asked/behavior that gets in the way of having a conversation
- Using slurs
- Making light of serious issues, especially mental health
- Spread harmful messages (antivax, villainization of topics or groups of people, etc)
