How to Block an Abuser Online Without Losing Evidence

Document Before You Block

When you block someone, their messages, posts, and sometimes even their profile may disappear from your view. Capture what you need first.

• Take screenshots with the username, full web address, date, and time visible.
• Save the profile link and account ID, not just the display name.
• Capture the conversation history, not just the latest message.
• Save voicemails, emails, and attachments.
• Record the pattern: how often, what times, and which platforms.
• Store copies where the person can't reach them.

Block, Mute, Restrict: Know the Differences

Platforms offer different tools, and the right one depends on your situation.

• Block stops the person from contacting you or seeing your profile in most cases, but they may notice.
• Mute hides their content from you without alerting them, which can be useful if you want to avoid a reaction.
• Restrict or limit reduces what they can see and send, with fewer signals.
• Report asks the platform to review the account for violating its rules.

If you fear a reaction, muting while you document and plan may be safer than blocking immediately. If you are in immediate danger, call 911.

Tighten Your Privacy Settings

Blocking works better when your account is less visible.

• Set your profile to private, or limit who can see posts, followers, and friends.
• Turn off location tagging and check-ins.
• Limit who can tag you or send you messages.
• Review your friends and followers, and remove people you don't trust.
• Check your connected apps and remove unfamiliar ones.
• Secure your account with a strong password and multi-factor authentication. The Cybersecurity and Infrastructure Security Agency's Secure Our World pages explain how.

Expect New Accounts and Workarounds

Many people who are determined to reach you will create new accounts, use other people, or move to a new platform. That is not your failure, and it is useful evidence of intent.

• Save and report each new account.
• Note the timing: new accounts that appear soon after you block someone are significant.
• Don't reply to them.
• Watch for contact through mutual friends. See stalking by proxy.

Blocking and Your Legal Case

Some people worry that blocking will hurt their case. In general, it doesn't. A block is a clear signal that contact is unwanted, and contact that continues afterward can support a finding of stalking or harassment. What matters is that you preserve the evidence. Stalking is a crime in all 50 states, and your records show the pattern. See how to prove stalking.

When Blocking Isn't Enough

Blocking can't stop a person from showing up, using other people, or posting about you elsewhere. If the contact is persistent or frightening:

• Report to the platform and to police. See how to report online stalking.
• File a complaint with the FBI's Internet Crime Complaint Center for internet crime.
• Ask about a protective order. See protection against stalking.
• Update your safety plan.

Using Filters and Helpers

You don't have to read everything. Use filters to hide messages from unknown accounts and to catch certain words. Ask a trusted friend to review messages and save evidence if reading them is too upsetting. Make sure that friend uses a secure account and doesn't engage.

If You're Tempted to Unblock

You might want to unblock to see what the person is saying, or to respond. Be cautious. Unblocking can invite more contact and can open the door to manipulation. If you need to monitor for safety reasons, ask a trusted person to do it, or use a method that doesn't give the person access to you.

Thinking Across Different Kinds of Platforms

Platforms differ, but the questions you should ask are similar everywhere.

• Social networks: Can I block, mute, or restrict this person? Can I control who sees my posts, followers, and tags?
• Messaging apps: Can I block the contact and prevent unknown numbers from messaging me? Does the app notify the person?
• Email: Can I filter messages from this address into a folder rather than my inbox, so that I keep evidence without reading them?
• Dating and meeting apps: Can I unmatch, report, and hide my profile from this person?
• Gaming and community platforms: Can I mute voice chat, block usernames, and limit friend requests?
• Phone: Can my carrier or phone block numbers, and can I silence unknown callers?

Each platform's menus change, so check its help pages, and follow the Social Media Reporting Guide for reporting steps.

Blocking Phone Numbers and Email

For calls and texts, block the number after saving the log. If the person uses new numbers, note them, and consider asking your carrier about options for filtering. For email, set up a rule that moves messages from the address to a folder, so your inbox stays calm and your evidence stays safe. Avoid changing your main number or email unless you have a plan, because the stalker may already know your new details through friends or accounts.

Protecting Family and Shared Accounts

Blocking only helps if the whole circle is protected. Ask family and close friends to block the person too, and to avoid sharing information. Check shared accounts, such as family photo albums or streaming services, for places where the person could see activity. Children's accounts can also be a route to you, so help them tighten settings. Read stalking by proxy for how stalkers use others.

When You Have to Stay in Contact

Sometimes you must communicate with the person, for example a co-parent. In those cases:

• Keep communication to logistics only, such as pickups and schedules.
• Use one channel, ideally written, so that there is a record.
• Be brief and neutral. Don't respond to provocations.
• Keep copies of every message.
• Ask your attorney or the court about structured communication or exchange arrangements.
• If a protective order exists, follow its terms about permitted contact.

A Safe Blocking Routine

1. Save screenshots, with usernames and dates.
2. Note the account in your log.
3. Report the account to the platform.
4. Block or mute the account.
5. Tighten your privacy settings.
6. Tell a trusted person.
7. Review again in a week for new accounts or contact through others.

Helping Children and Teens Block and Report

Young people are often targeted by persistent contact, and they may not tell adults. Make sure children and teens know that blocking is okay, that they won't be punished for reporting, and that they should save messages before blocking. Help them set accounts to private, limit who can message them, and report abusive accounts. If the contact is persistent, threatening, or sexual, report to the platform and police, and save everything. School counselors and resource officers can also help.

Mistakes to Avoid When Blocking

• Blocking in a rush and losing evidence. Take screenshots first.
• Announcing the block. A dramatic message can provoke the person.
• Ignoring other channels. Block on phone, email, and every platform, not just one.
• Forgetting shared contacts. Friends may keep passing messages.
• Giving up on reporting. Blocking without reporting leaves the account active for others.
• Going back to check. Peeking at the person's profile can feed the cycle and can expose you.

A Final Reminder

Blocking is one tool among many. If the contact continues across new accounts or devices, treat that as information, not as a failure on your part. Keep your records current, tell someone you trust, and take the next step: report, seek an order, or update your plan.

Blocking removes a door. Documenting and reporting build the walls.
