Comment filters and keyword blocking, explained
TikTok's comment filters let you automatically hide comments that look like spam or are offensive, and block specific keywords you choose, so they do not appear publicly on your videos. You can also limit who can comment and review filtered comments, depending on current settings.
Why filters beat deleting one by one
Deleting rude comments by hand works when you get five a day. When a video takes off and hundreds pour in, you cannot keep up, and one cruel line can ruin your evening.
Filters work in the background, catching many problem comments before you or your viewers ever see them.
The main types of filter
TikTok has offered a filter for spam and offensive comments, a keyword filter where you list words or phrases to hide, and options to hold all comments for your approval. Names and exact options change between versions.
Keyword filters are the most personal. Add nicknames people use to mock you, slurs, competitor shop names or anything that keeps causing trouble.
Choosing who can comment
Beyond filters, you can usually choose whether everyone, only friends or nobody can comment, either for your whole account or for a single video. This is useful when a video touches a sensitive topic.
For a personal account, limiting comments to friends can make TikTok feel much safer without going fully private.
Keeping your settings working
Review your keyword list every month and add new words that slip through. Spammers often change spelling, so add common variations too.
Check filtered comments occasionally in case a genuine question was hidden by mistake. Find these tools under privacy or comment settings in the current app.
Frequently asked questions
Can people tell their comment was filtered?
Usually the commenter can still see their own comment, while others cannot. This helps reduce arguments, but behaviour may vary by version.
Do filters work on old videos too?
Filters generally apply to new comments across your videos, but older comments that already appeared may need to be removed by hand.
