Online harassment can be a pile-on in your comments, threats in your messages, or doxxing: someone publishing your home address, phone number or other private details to harm you. This guide helps you see what can be found about you, limit who can reach you, keep evidence and get help. It doesn't cover what the law says; if you want to take legal steps, talk to a lawyer. If you are in danger now, start with If your address is exposed.

PEN America suggests looking for yourself the way an attacker would, before an attack if you can.

  1. Search for your name and its variations, phone numbers, current and past addresses, email addresses and usernames. Use more than one search engine, and search while signed out.
  2. Look at image results, and at old CVs and PDFs that list your address or phone number.
  3. CPJ suggests looking up close family members too, including anything that shows their link to you.
  4. EFF suggests username search sites, such as What's My Name or Namechk, to find accounts in your name, including fake ones.
  5. Don't upload sensitive or private photos to reverse-image or face-search services. EFF notes these services scan and store the photos you give them, though it may be worth it if your pictures are being shared against your will.
  6. If it is available where you live, Google's Results about you can alert you when your phone number, address or email appears in Google Search. You give Google these details to look for; Google says it doesn't share them or use them to personalise its other products. It is offered to adults in some countries only.

Much of the advice about data brokers, sites that sell personal details, is about the United States. Set a reminder to repeat the search: new results appear over time.

These settings make an attack harder to join and to see. They don't remove posts about you elsewhere, and they don't stop screenshots.

Instagram

  1. Limits: tap Profile, then Menu, and under How others can interact with you tap Limit interactions. Choose what to limit and who, such as Recent followers or Accounts that don't follow you, then Turn on. It lasts up to four weeks at a time. Instagram says limited accounts aren't told. It isn't available on computers.
  2. Restrict one person: in your chat with them, tap their name, then Options and Restrict. Or tap and hold one of their comments and choose Restrict account. Their new comments are visible only to them unless you approve them.
  3. Hidden words: in Menu, under How others can interact with you, tap Hidden words and add words to hide. Anyone can still open hidden comments with View hidden comments.

X

  1. Protect your posts: on iPhone, tap your profile photo, then Settings and privacy → Privacy and safety, and under Audience and tagging turn on Protect your posts. People who already followed you still see your posts, and links to your photos and videos still work for anyone who has them.
  2. In Notifications, tap the gear icon to turn on the quality filter, and use Advanced filters to mute notifications from new accounts, accounts that don't follow you, and accounts without a confirmed email or phone number.

TikTok

  1. Tap Profile, then Menu ☰ → Settings and privacy → Privacy → Comments. Under Allow comments from, choose Friends (followers you follow back), or Followers if your account is private, and turn on the comment and keyword filters. TikTok says some filters aren't available to everyone.

Facebook

  1. Profile Lock is offered only in some countries, and Meta doesn't say which. With it, only friends see your photos, posts and stories, and old public posts change to Friends. Without it, see Choose who sees your posts and Review tags before they appear.

All accounts

  1. Attackers often try to break into accounts as well. Turn on two-step verification and stop using SMS codes where you can: see Turn on two-step verification and Remove SMS where you can.

Hidden comments are hidden from you too, so you may miss a real threat. EFF and the Online Violence Response Hub suggest asking someone you trust to watch your accounts for you.

Platforms or the attacker may delete posts, especially after you report them. PEN America says to save evidence first.

  1. Take screenshots that show the content, the account name, the date and the web address, and save the links, especially to the attacker's profile.
  2. Keep a log: date and time, platform, account, what happened, and whether you reported it.
  3. Keep the whole exchange, not only the parts that help your side, PEN America advises.
  4. Don't forward a threatening email: PEN America says you could lose details in its header, such as the address it came from. Keep the original and copy its text if you need to share it.
  5. PEN America suggests keeping sensitive material, such as intimate images, on an external drive rather than in the cloud.
  6. Collecting evidence can be painful. PEN America suggests asking someone you trust to help.

Delete posts or close accounts only after you have saved what you need. If someone watches the forums where an attack is organised, EFF suggests using Tor Browser and not engaging with anyone there: see Use Tor Browser safely.

Reporting creates a record and can get content removed, though PEN America says to be ready for no helpful result. Where you can add text, name the rule the content breaks.

X

  1. On a post or an account, tap the more icon, then Report. For a message, tap and hold it, then Report message.
  2. X includes the reported posts in its follow-up emails. If someone else can read your email, or you don't want to see the posts again, untick Updates about this report can show these posts.
  3. Blocked accounts aren't notified, but they see the block if they visit your profile, and they can still see your public posts. Muting is invisible to them.

Instagram

  1. Instagram says reports are anonymous: the account won't see who reported it. Posting someone's private address, phone number or email breaks its rules, and you can report it if it is yours. Instagram says not every case counts, and it can't remove anything from other sites.

Facebook

  1. To block someone, go to their profile, tap ••• and Block. Facebook says they aren't notified. Blocking doesn't cover groups, apps or games you both use.

TikTok

  1. To block someone, go to their profile, tap Share and Block. To block many at once, tap and hold a comment, then Manage multiple comments → More → Block accounts. TikTok says blocked people aren't notified.

All platforms

  1. PEN America warns that blocking can make harassment worse when attackers notice it and show it off. Muting, hiding or restricting can be quieter.
  2. Don't reply to attackers, especially if you feel physically threatened, and don't ask them to remove your details, even if a platform suggests it. PEN America says engaging can make the abuse worse.

Blocking and muting don't stop posts about you from spreading, and you may stop seeing them.

The Online Violence Response Hub says the risk is greater if the attacker is nearby or can travel to you.

  1. Look at the threat with someone you trust. PEN America suggests asking: does it name you, does it include details about you or your family, and is it getting worse?
  2. If you fear for your safety at home, stay somewhere else for a while, such as with friends or family or at a hotel. The Hub suggests leaving for 24 hours and then looking at the situation again.
  3. Tell someone when you leave, where you are going, and when you are back. Don't post about where you are.
  4. Before you go back, ask someone to check whether anyone is waiting near your home.
  5. Plan ahead where you would go and how you would leave your home. Vary your routes, for example to work.
  6. Decide with people you trust whether contacting the police is safe for you.

The Hub warns that attackers often keep looking for more details after doxxing, including by breaking into accounts: keep If your account was hacked at hand.
