On Mastodon, if you have posted in a thread or been tagged in it, but you don’t want to take part any more, you can mute the conversation so that you won’t get notifications from it. No one will know you’ve done this, and it will only affect that thread:
- Log in through your server’s website (and some apps also include this feature)
- Go to one of your posts in the thread you want to mute
- Click ⋯ and select Mute conversation
- If you haven’t posted in the thread, go to a post in the thread where you were tagged, then select ⋯ and Mute conversation
- If you still can’t find this option, go to your Notifications section, then click ⋯ and Mute conversation on one of the conversation’s posts there
If you change your mind, just do the same thing again but select Unmute conversation.
