Join the conversation
Open the comments for the post or video you are viewing. Check the content and account before writing, especially after moving quickly between clips. Keep a comment relevant, readable and respectful; the community guidelines apply to replies as well as original posts.
Use Reply when you want to respond to a particular comment, where that action is available. A reply’s place in a thread matters: it helps other readers understand whom you are addressing. Avoid posting private contact details, someone’s location or sensitive information about a child.
Wait for a posting result
A pending comment, sending indicator or text in the input field does not prove publication. Wait for the app’s result and check the thread before retrying after a connection failure. Repeated taps can make a conversation confusing, even when the first response was merely delayed.
If posting fails, retain your wording separately and note the exact error. Check Account Status if the app explicitly reports a restriction; an ordinary network error is not proof of one. Use support for a repeated technical problem.
Handle unwanted behaviour
Use the comment’s Report action when the current screen provides one, then follow the reporting guide. Reporting is a request for moderation, not an immediate removal guarantee. Review blocking and privacy controls for unwanted contact. Content owners should use only the moderation controls actually available to them; not every comment screen offers pinning, deletion or audience management.
