How do you enable or disable tweet replies on Twitter?

 Twitter doesn't have a native feature to disable replies to individual tweets. However, there are a couple of options you can consider:

1. **Protected Tweets**: You can protect your tweets, which means only your approved followers can see your tweets and reply to them. To protect your tweets:
   - Go to your Twitter settings.
   - Under the "Privacy and safety" section, select "Audience and tagging".
   - Check the box next to "Protect your Tweets" to make your tweets private.

2. **Limiting Audience**: You can limit your audience by adjusting your tweet's privacy settings:
   - When composing a tweet, click on the globe icon (public) next to your tweet composing box.
   - Change the audience to "People you follow" or "Only people you mention" to limit who can reply to your tweet.

Remember that these methods restrict who can see and reply to your tweets, rather than disabling replies altogether. If you want to control who can reply to your tweets more directly, you might consider using Twitter Lists to manage interactions or post your content on platforms that offer more granular control over replies.
