Why Do My YouTube Comments Keep Disappearing?

A comment you posted disappearing is frustrating, but it almost always comes down to one of a few specific causes.

Most Likely Causes

Held for review — the creator has comment moderation turned on, and your comment is awaiting manual approval. It may not be missing at all, just not yet approved.
Automatically flagged as spam — YouTube’s spam filters can catch comments with links, certain words, or patterns common in spam, even if the comment was genuine.
Removed by the creator — channel owners can delete or hide individual comments on their own videos at any time.
Comments disabled or restricted — some creators turn off comments entirely, or restrict them to subscribers or approved commenters only.
Your account has a restriction — if your account has been flagged for violating YouTube’s policies, your comments across the platform may be hidden from others even though you can still see them yourself.

Try viewing the video and your comment while signed out, or from a different account — if you can see it but others can’t, it was likely flagged or held for review rather than deleted.
Check if comments are disabled entirely on that video (no comment section at all means the creator turned them off, not that yours specifically was removed).

Avoid posting links or repetitive text, which are the most common triggers for spam filters.
If you believe your account was wrongly restricted, check YouTube Studio > Settings > Channel > Advanced settings for any noted strikes or restrictions.
If none of the above applies, it may simply be a temporary glitch — try reposting once, but avoid repeatedly reposting the same comment, which can itself trigger spam detection.

Not always — it could be held for review or flagged as spam rather than removed.

Try viewing it from a different account or signed out; if you can see it but others can’t, it was likely flagged rather than removed.
