1. How it usually happens
You are monitoring a listing, maybe you have already paid or are negotiating. Then suddenly: "content unavailable". Or the seller's profile vanishes, or your account is blocked without warning.
This type of situation has a peculiarity: the problem is not just what happened, but the fact that it is no longer visible. It is like trying to prove the existence of a billboard that was removed overnight.
From the platforms' perspective, removals and suspensions can happen for many reasons: reports, automated checks, errors. From the user's perspective, only a blank screen or a generic message remains.
A frequent anecdote: many users realise too late that they never saved the advert or the page. When it is needed, it only exists in their memory.
2. What you need to prove
Here the goal is twofold: to prove that the content existed and that it was removed or made inaccessible.
You must be able to prove:
- the existence of the account, listing, or content
- its content (description, images, conditions)
- the link to a transaction or communication
- the time it was accessible
- the fact that it is no longer available
- any error or removal messages
Basically, you must build a "before and after": what was there and what changed.
3. What to collect
You need to collect both what existed and what shows its disappearance.
- Screenshots of the page or listing (before removal, if available)
- Photos and descriptions of the content
- Full URL of the page
- Screenshots of the profile or account
- Chats with the other party
- Emails received (confirmations, notifications, alerts)
- Screenshot of the error message or unavailable content
- Any proofs of payment or agreement
- Saved copies of terms or offer details
A useful detail: even a simple "page not found" screenshot becomes significant if linked to the previous content.
4. How to proceed
Speed is important, but order is also needed.
As soon as you notice the removal:
- Take screenshots of the unavailable page
- Save the exact URL
- Check if you have previous copies (chats, emails, images)
If you have access to previous content:
- Retrieve everything showing the original content
- Put the evidence together in chronological order
Then organise:
- Separate the "before" and "after" material
- Give files clear names (e.g., date + description)
- Keep original files
To strengthen documentation:
- Use ExistBefore to timestamp screenshots, chats, and key documents
- Keep an organised copy ready for use
An effective approach is to imagine reconstructing a scene: first the advert was there, then it disappeared, and you have traces of both moments.
5. Mistakes to avoid
Some mistakes make it difficult to prove the situation:
- Not saving the content while it is still visible
- Taking screenshots without URL or context
- Ignoring error messages after removal
- Mixing files without chronological order
- Modifying original files
An important tip concerns completeness: even seemingly trivial elements, like a link or a date, can become central.
Timestamping content at the right moment allows you to preserve a clear, usable trail at no cost.
6. After documenting
Once everything is collected, you can act with greater precision.
- Contact the platform to ask for clarification on the removal
- Provide the collected evidence in an orderly manner
- If it involves a transaction, contact your payment provider
- Keep everything for potential developments or disputes
- Consider seeking support from consumer associations
At this point, you are no longer trying to remember what was there: you are showing a concrete sequence of what existed and how it disappeared.
