To avoid losing track of blocked users in the future, maintain a private note of usernames you block, as YouTube no longer provides an internal list. End of Document
Version: 1.0 Date: 2023 Platforms Covered: YouTube Web (Desktop), YouTube Mobile App (Android & iOS) Prerequisites: An active YouTube account, being logged in, and having previously blocked the user. 1. Introduction YouTube’s blocking feature (introduced in 2019 and refined by 2023) prevents a specific user from commenting on your videos, replying to your comments, or sending you direct messages (if applicable). Unblocking a user reverses these restrictions, allowing normal interaction. Unlike muting, blocking is bidirectional for comments (they cannot see your future comments, and you cannot see theirs, though old comments may reappear after unblocking).
