To block someone on TikTok and stop them from interacting with you, you can use TikTok’s built‑in blocking tools. Below is a simple, step‑by‑step guide plus extra privacy tips to keep your account safe.

# What Happens When You Block Someone on TikTok?

When you block a user on TikTok:

  • They can’t view your profile, videos, or likes.
  • They can’t comment, like, or send you direct messages.
  • They won’t be notified that you blocked them (but they may notice they can’t interact with you).
  • Any existing comments and messages remain, but new interactions are blocked.

# How to Block Someone on TikTok (Mobile App)

These steps work on both iOS (iPhone) and Android:

# Method 1: Block from the user’s profile

  1. Open TikTok and log in.
  2. Go to the profile of the person you want to block:
    • Tap their username from a comment, DM, or search for them using the Search icon.
  3. On their profile, tap the three dots (⋯) or three lines (☰) in the top‑right corner (icon may differ by version).
  4. Tap Block.
  5. Confirm by tapping Block again.

You’ve now blocked that user; they can’t view or interact with your content.

# Method 2: Block from a comment

If someone is harassing you or spamming your comments:

  1. Locate the comment on your video.
  2. Long‑press (tap and hold) on the comment.
  3. Tap Manage multiple comments or More (depending on your app version).
  4. Select the profile you want to block.
  5. Tap Block and then Confirm.

# Method 3: Block from a direct message (DM)

  1. Open TikTok and go to your Inbox.
  2. Open the chat with the person.
  3. Tap their profile picture or username at the top to go to their profile.
  4. Tap the three dots (⋯) or three lines (☰) in the top‑right corner.
  5. Tap Block → Confirm.

# How to Block Multiple Accounts at Once

If you’re facing spam or harassment from many accounts, TikTok allows bulk blocking from comments:

  1. Go to the video where the unwanted comments appear.
  2. Long‑press a comment.
  3. Tap Manage multiple comments.
  4. Select up to 100 comments at a time.
  5. Tap More (if presented).
  6. Choose Block accounts → Block to confirm.

This is very useful against spam or coordinated harassment.

# How to Unblock Someone on TikTok

If you change your mind:

  1. Open TikTok and go to your profile.
  2. Tap the three lines (☰) in the top‑right corner.
  3. Go to Settings and privacy.
  4. Tap Privacy → scroll down to Blocked accounts.
  5. You’ll see a list of everyone you’ve blocked.
  6. Tap Unblock next to the user you want to restore.

You can also go to their profile and tap Unblock directly.

# Extra Privacy Tips to Avoid Unwanted Attention

Blocking is one tool; adjusting your settings can prevent future issues. Here’s how to tighten your TikTok privacy:

# 1. Make your account private

With a private account, only people you approve can follow you and see your content.

  1. Go to Profile → ☰ (Menu) → Settings and privacy.
  2. Tap Privacy.
  3. Turn Private account ON.

# 2. Control who can comment, message, and mention you

In Settings and privacy → Privacy, review:

  • Comments:
    • Set to Friends or No one if you’re dealing with harassment.
  • Direct messages:
    • Choose Friends or No one.
  • Mentions and tags:
    • Limit to Friends or No one to reduce unwanted tags.
  • Who can view your liked videos:
    • Set to Only me if you don’t want others to see what you like.

# 3. Filter and review comments before they appear

You can auto‑filter or manually approve comments:

  1. Go to Settings and privacy → Privacy → Comments.
  2. Enable:
    • Filter spam and offensive comments
    • Filter keywords (add specific words/phrases you don’t want to see)
    • Filter all comments if you want to approve each comment manually.

# How to Report Abusive or Harmful Accounts (Besides Blocking)

If someone is breaking TikTok’s rules (hate speech, threats, bullying, sexual content, scams), you should report them in addition to blocking:

# Report a user profile

  1. Go to the person’s profile.
  2. Tap the three dots (⋯) / three lines (☰).
  3. Tap Report.
  4. Choose a reason (e.g., Bullying or harassment, Hate speech, Scam or fraud).
  5. Follow the prompts to submit.

# Report a specific video, comment, or message

  • Video: Tap Share → Report.
  • Comment: Long‑press the comment → Report.
  • Message: Long‑press the message → Report.

# Quick FAQ: Blocking on TikTok

1. Does TikTok notify someone when you block them?
No. TikTok does not send a notification. They may realize it if they try to visit your profile or interact with you and can’t.

2. Can a blocked user see my old videos?
No. Once blocked, they should not be able to view your profile or videos while they remain blocked.

3. Can a blocked person still message me?
No. Blocking prevents them from sending you new messages.

4. Will blocking remove their old comments?
Blocking does not always delete existing comments automatically. You may need to manually delete any unwanted comments from your videos.

5. Does blocking remove them as a follower?
Yes. Blocking automatically removes them from your followers and prevents them from following you again (unless you unblock them).

# Summary: Best Practices for Staying Safe on TikTok

  • Block users who harass, spam, or make you uncomfortable.
  • Report accounts that violate TikTok’s rules.
  • Use a private account if you want full control over who sees your content.
  • Adjust comment, DM, and mention settings to reduce unwanted contact.
  • Use comment filters to automatically screen out offensive or spammy content.
