As mentioned, when you block someone on Twitter, they won't receive a notification about it. But they can search your profile and establish they've been blocked. If you don't want to see a person's tweets or comments, you can remove them from your feed by muting them. That way, you won't block them, but you won't be able to see their posts on your timeline. Users with muted accounts won't know you've muted them. Muting an account doesn't mean unfollowing it. The person remains on your followers' list, but you won't see any updates. Also, they'll still be able to message you, mention or reply to you, and you'll still receive notifications about it. You can also mute an account you're not following. In that case, you won't receive notifications about replies and mentions by that person. Users can mute someone from a tweet or a profile. Here's how to mute from a tweet: 1.
