Where to go, and who handles what.
Every organisation on this page is real, independent of Zolsi.CC, and listed with what it actually does. Several are free and anonymous. Nothing here needs an account, and none of it costs money.
If a child is in immediate danger right now, call your local emergency number - 112 across the EU, 999 in the UK, 911 in the US and Canada. Do that first. Everything on this page can wait until afterwards.
Four things that make the next step easier
- Stop the contact. Do not reply, negotiate or pay. Do not confront the person, which warns them.
- Keep the evidence. Screenshot the messages, the profile, the username and any links, before you block. Do not delete the conversation.
- Do not forward any image of a child, to anyone, for any reason, including to show an adult or the police what happened. Describe it instead. Possessing or passing on such material is a serious offence whatever the intention, and the organisations below have lawful ways to deal with it.
- Write down what happened while it is fresh: dates, app names, usernames. You will be asked, and it is hard to recall later.
Reporting abuse or exploitation
Use these when a child is being sexually exploited online, or when you have found sexual images of a child.

Worldwide
CyberTipline
The reporting line of the National Center for Missing & Exploited Children, the United States clearing house for child sexual exploitation reports. It accepts reports of online enticement, sextortion, trafficking and sexual images of children, and passes them to the appropriate law enforcement agency.

United Kingdom
Internet Watch Foundation
A UK charity that finds and removes child sexual abuse images and videos from the internet. Reports can be made completely anonymously - you are not asked who you are, and you do not need to explain how you found the material.
Report anonymously -
United Kingdom
CEOP Safety Centre
Part of the UK National Crime Agency. This is where to go if a child is being contacted or pressured sexually online, rather than where to report images. A child protection advisor reads every report. Children and young people can report for themselves, and so can adults worried about a child.

INHOPE
The international association of internet hotlines, with member hotlines in more than fifty countries. If you are not in the UK or the US, start here to find the organisation that takes reports where you live, in your own language.

Getting an image taken down
Both services below work the same clever way. Your device calculates a digital fingerprint of the image and only that fingerprint is sent. The picture itself never leaves your phone or computer and nobody at either organisation sees it.

Under 18 in the image
Take It Down
For anyone who has a nude, partly nude or sexual image of themselves that was taken when they were under 18. Participating platforms use the fingerprint to find and remove matching copies. Free, and you stay anonymous. You do not need a parent to start it.
Start a case -
18 or over in the image
StopNCII.org
The same idea for intimate images shared without consent where the person was 18 or older when the image was made. Run by the Revenge Porn Helpline, part of the UK charity SWGfL, and used by major platforms worldwide.

If you just need to speak to a person
You do not have to be in a crisis, and you do not have to know what you want to say. These lines exist for exactly the conversation you are not sure how to start.

How it is kept honest
Every organisation here was checked against its own website in August 2026, and nothing is listed that could not be confirmed there. Phone numbers and opening hours do change, so if you are relying on one, open the organisation’s own site through the link and confirm it before you call.
Zolsi.CC has no relationship with any of these organisations, receives nothing for listing them, and cannot see or act on anything you send to them. If you find an entry that is out of date or wrong, that is a fault worth fixing quickly.
Not on this list
This is deliberately short. There are many good organisations working on internet safety, and a page listing forty of them helps nobody at the moment they actually need it. These are the ones that cover the most ground, take reports from the widest range of countries, or lead to a local service that does.
