How per-buyer marking works
The mark goes in first. The answer comes later.
You can only find whose copy leaked if every buyer got a different copy. That has to happen before the leak, not after.
-
Every buyer gets their own copy
You upload the file to Trace once. Each buyer’s copy of your video, photo or voice note carries its own invisible mark. Fans see the same file, and you upload it to your platform yourself.
-
A copy turns up online
On a leak site, in a group chat or as a tube re-upload. Paste the link or upload the file into Trace. Downloads, screen-recorder captures and re-encodes of the same file are the leaks it is built for.
-
Trace shows whose copy it was
When several checks agree, Trace shows which account the leaked copy was delivered to. When they don’t, it says inconclusive and shows no account.
What a match shows
Whose copy it was. Not a guess.
A match is read from the leaked file itself. It points at the copy you delivered, so it says which account received it, not who pressed share.
The copy and the checks
The copy ID that read back, and the checks that had to agree before an account was shown.
An evidence pack
Hashes, dates and the match record, ready for a platform report, your takedown service or a lawyer. How to check a pack
Inconclusive is a real answer
When the reading is weak, no account is shown. A no-match is not proof that a buyer didn’t share the file.
What it can’t do
Honest limits, before you start.
It doesn’t remove copies
Trace doesn’t take links down or file takedowns. It works alongside takedown services: they remove the copies, Trace shows whose copy it was. How the two fit together
Mass messages trace to a list
A mass message goes out as a handful of marked versions, one per fan list. A leaked copy traces to that list version, not to one account. How list versions work
Wall posts can’t carry a mark per viewer
A post on your wall or feed is one file the platform serves to every subscriber from its own servers. Everyone gets the same copy, so there is nothing per viewer to read back.
Old files and phone recordings
Files sent before you started marking have no mark to read. A phone filming a screen often comes back inconclusive. What we tested
Leak economics
One leaked copy can cost most of a drop.
Example numbers, to show the shape of it. They are not data from Trace users, and your prices and fan counts will differ.
Example: the drop
$3,000
A $25 PPV that 120 fans would buy. $25 × 120 = $3,000.
Example: the free copy
80 fans
One buyer’s copy is online the next day. Say about 80 of the 120 find it and never pay.
Example: lost on one drop
≈ $2,000
80 × $25 = $2,000 that never comes in. And the same account gets your next drop.
A takedown removes that copy. It can’t tell you whose copy it was, so the source keeps getting new drops. Knowing which account the leaked copy was delivered to is what lets you block and report it, so the next drop doesn’t go the same way.
After a match
You decide what happens next.
Trace never files, posts or messages anything for you. A match gives you something you can act on.
Block and report
Stop sending to that account. Report the real paying account to the platform, with the evidence pack and a platform letter attached.
Remove the copies
Give the leaked URLs to your takedown service, or send notices yourself. DMCA guide
Keep the record

FAQ
Finding who leaked, short answers.
Can I find out who leaked my OnlyFans content?
Only if each buyer got their own marked copy before the leak. Trace puts an invisible mark in every buyer’s copy. When a copy turns up, Trace shows which account that copy was delivered to. It shows whose copy it was, not who pressed share.
What does a match show?
Which account the leaked copy was delivered to, the copy ID, and the checks that agreed, with an evidence pack you can give a platform, a takedown service or a lawyer. When the checks don’t agree, Trace reports the result as inconclusive and shows no account.
Does Trace remove leaked content?
No. Trace doesn’t remove copies or file takedowns. It works alongside takedown services: they remove the copies, Trace shows whose copy it was.
What about mass messages and wall posts?
A mass message goes out as a handful of marked versions, one per fan list, so a leaked copy traces to a list version, not to one account. A wall or feed post is one file the platform serves to every subscriber, so it can’t carry a mark per viewer.
Can Trace trace content I sent before I started?
No. A file sent without a mark has nothing to read back. Mark every new drop from now on, and use takedowns for what is already out.
Does Trace need my OnlyFans or Fansly login?
No. Trace never asks for your OnlyFans or Fansly password and never logs in, posts or messages inside those platforms. You mark files in Trace and upload them yourself. Read the policy.
How do I start?
Start a 14-day trial. A card is required. If you only want to see what is already out there, the free leak scan takes about two minutes and needs no account.
