Step by step
- Test the URL itself first. Open the exact coomer.su URL you filed on, not the profile it sat under. A profile that still loads tells you nothing about whether the specific post came down, and that distinction is what a status record has to capture.
- Read the response, not the page. A removed page and a page that has been made private look similar from the outside. What separates them is the response the server gives, which is why an automated check records the status rather than a screenshot.
- Search for the URL separately. Search the exact coomer.su URL to see whether the search index still holds it. Search removal and host removal are different processes with different queues, and one landing says nothing about the other.
- Re-check after a few days, not once. A single check catches a removal that stuck and misses one that was reversed. Anything reported as removed on coomer.su is worth re-testing later, because the reversal is the event that costs you.
- Record the outcome against the notice. Tie each check back to the notice and round it belongs to. Without that link there is no way to tell which channel produced the removal, and that is the only information that makes the next takedown faster.
Why a status of sent is not a status of removed on coomer.su
Most takedown dashboards show what was sent, because that is what the system knows. openDMCA records the provider outcome instead — sent, failed, queued for a form, or skipped because it was throttled — and then verifies removal separately rather than inferring it from a successful send.
That verification is what feeds the Removal Graph. A coomer.su notice that was delivered and produced no removal is a data point; without it, the routing would keep treating the host as though the email rung worked.
A daily sweep re-checks URLs already marked removed. One documented limitation: the resurrection rate is computed from a URL's current status, so a link that came back and was removed again counts as removed. That measure under-reports, and openDMCA publishes it as under-reporting rather than rounding it up.
openDMCA gives the first two hops away: you can open confirm a removal actually landed and run it on a URL of your own, with no account and nothing uploaded.
One thing that catches people out on coomer.su
openDMCA throttles outbound notices to one email per recipient per client in any twenty-four hour window. On coomer.su, where every URL resolves to the same fallback address, that means forty separate URLs become one batched notice rather than forty emails — and a creator filing manually who sends them one at a time is far more likely to be filtered as bulk mail than one who batches.
