If you want to reduce spam, harassment, or unwanted conversations, you may be wondering: how do you block certain words on TikTok? TikTok includes a keyword filtering feature that lets you hide comments containing specific words or phrases from appearing on your videos.
Whether you’re a creator protecting your community or simply trying to keep discussions positive, blocking keywords can help you moderate comments more effectively. In this guide, we’ll explain how to set up keyword filters, what they do, and their limitations.
Can You Block Certain Words on TikTok?
Yes.
TikTok allows users to create a list of custom keywords that will automatically filter comments containing those words or phrases. You can also enable automatic filtering for comments that TikTok identifies as offensive or spam-like.
Keyword filtering helps you control the conversations taking place under your videos without having to manually review every comment.
How to Block Certain Words in TikTok Comments
Step-by-Step Instructions
- Open TikTok.
- Go to your Profile.
- Tap the Menu (☰) icon in the top corner.
- Select Settings and privacy.
- Tap Privacy.
- Choose Comments.
- Select Filter keywords.
- Tap Add keywords.
- Enter the words or phrases you want to block.
- Save your changes.
Comments containing those keywords may be hidden from public view.
How Keyword Filtering Works
When someone posts a comment containing one of your filtered words:
- The comment may be hidden automatically.
- Other viewers generally won’t see it unless you approve or adjust your settings.
- The user isn’t typically notified that their comment was filtered.
This helps reduce unwanted interactions without requiring constant moderation.
Can You Block Multiple Words?
Yes.
You can add numerous words and phrases to your keyword list, including:
- Offensive language
- Spam phrases
- Personal information
- Common troll comments
- Unwanted promotional terms
Updating your list regularly can improve its effectiveness.
Can You Block Hashtags or Emojis?
TikTok’s keyword filter primarily works with text and phrases. Support for hashtags, symbols, or emojis may vary depending on how the feature is implemented in your app version.
If a specific hashtag or emoji is causing issues, you may need to combine keyword filtering with manual moderation.
How to Turn On Automatic Comment Filtering
In addition to custom keywords:
- Go to Settings and privacy.
- Tap Privacy.
- Select Comments.
- Enable Filter all comments or Filter offensive comments, if available.
TikTok will use its own systems to identify comments that may be inappropriate or spam.
Can You Block Words in Direct Messages?
TikTok’s keyword filtering is mainly designed for comments. Direct message controls are managed separately through your privacy settings, where you can limit who can send you messages.
If someone sends abusive messages, blocking or reporting the account may be the best option.
Can You Edit Your Keyword List?
Yes.
At any time, you can:
- Add new words
- Remove old keywords
- Update phrases
- Adjust filtering preferences
Reviewing your list periodically helps keep moderation relevant.
Tips for Better Comment Moderation
Include Common Variations
People may misspell offensive words intentionally, so consider adding common variations to your filter list.
Review Hidden Comments Occasionally
Legitimate comments can sometimes be filtered accidentally, so it’s worth checking your hidden comments from time to time.
Combine Filters with Privacy Settings
Restricting who can comment can further reduce unwanted interactions.
Block Repeat Offenders
If a user repeatedly bypasses your filters, blocking them may be more effective than relying on keyword filtering alone.
Common Problems
Filtered Comments Still Appear
Double-check that:
- The keyword is spelled correctly.
- The filter is enabled.
- The comment contains the exact word or phrase you’ve added.
Can’t Find the Keyword Filter
Some features vary by region or app version. Updating TikTok may make additional moderation tools available.
Too Many Legitimate Comments Are Hidden
Review your keyword list and remove words that may unintentionally match harmless conversations.
