Why TikTok puts comments "under review"
TikTok uses an automated moderation system that scans every comment posted on the platform. When a comment triggers the moderation system — by containing prohibited language, matching a known violation pattern, or being flagged by other users — TikTok places it in an "under review" state.
During this state, the comment is not visible to the general public. The poster may see a message saying "your comment is under review" or the comment may simply appear to have been posted but is invisible to everyone else. TikTok does not provide a timeline for how long the review takes — it can range from minutes to days.
Common triggers for comment review
TikTok's moderation system flags comments based on several criteria:
- Language that matches community guideline violation patterns (profanity, hate speech, threats)
- Links — especially external links or shortened URLs
- Comments reported by other users (a single report can trigger review)
- Comments from accounts with prior community guideline violations
- High comment velocity from a single account (mass-commenting pattern)
- Comments matching known spam or scam templates
The challenge for brands on TikTok
TikTok's "under review" system is platform-level moderation — it protects TikTok's community guidelines, not your brand. A comment saying "this product is overpriced and Brand X is better" will never trigger TikTok's review system because it does not violate any community guideline. But for your brand, it is a competitor redirect actively costing you conversions.
TikTok's own comment filter (Settings → Privacy → Comments) adds a keyword layer, but it only blocks exact matches. Between TikTok's automatic review and the keyword filter, brands typically catch less than 40% of the comments that are actually harmful to their business. The other 60% — competitor bait, coded slurs, emoji attacks, dropshipping callouts — require AI context to catch.
FeedGuardians operates alongside TikTok's native moderation. While TikTok reviews comments for community guideline violations, FeedGuardians reviews comments for brand safety — competitor bait, coded attacks, multi-language spam, scam pitches, and emoji-chain attacks that TikTok's moderation ignores entirely. Both systems run simultaneously, catching different categories of harmful content.

Frequently asked questions
There is no published timeline. Some comments are reviewed within minutes; others sit in review for days. TikTok does not provide a way to check the status of a comment under review.
As a poster, you may see a "comment under review" message where your comment would normally appear. As a creator/brand, you cannot see a queue of comments under review on your own posts — TikTok manages this internally.
No. Under review is a temporary state. The comment may be approved (becomes visible) or removed (deleted). While under review, it is invisible to the public but not permanently deleted.
You can report comments, which may escalate them in TikTok's review queue. However, TikTok does not provide transparency into how reports affect review timing.
Yes. TikTok Shop product listing comments go through the same moderation system. A product question flagged for review is invisible to potential buyers until approved — which can directly hurt conversion rate.
