How do you report a tweet that encourages self-harm or suicide?

Twitter takes the issue of self-harm and suicide seriously and provides a way for users to report such content. Here's how to report a tweet that encourages self-harm or suicide:

1. Go to the tweet you want to report.
2. Click the three-dot menu icon below the tweet.
3. Select 'Report Tweet.'
4. Choose 'It's abusive or harmful' as the reason.
5. Then, select 'Harassment' as the sub-reason.
6. In the next step, you'll be asked to specify what type of harassment it is. Select 'Suicide or self-harm.'

If you believe the user is at immediate risk, you should also contact your local authorities or a suicide prevention hotline. Twitter reviews reports and may take enforcement actions based on their policies and guidelines.
