Four ways to stop

How What it stops When Content already collected
Email the operator Everything, for the URL or the whole origin On receipt, exclusion recorded first Text purged, excluded from every later export
A robots.txt Disallow for CrawlCharter Fetching On the next policy read Quarantined on the next re-check if it covers the collected paths
A well-known AI policy denying training Training use only On the next policy read Quarantined on the next re-check
A TDM reservation Training use only On the next policy read Quarantined on the next re-check

What happens to content already collected

A quarantine keeps the text and stops using it. A takedown destroys the text. Ask for removal and you get a takedown.

Aspect Takedown Quarantine
Trigger a verified removal request, or a decision by DEVAesia the policy the origin published became more restrictive
Stored text purged retained
Stored decision tombstoned left intact as the record of collection time
Reversal never manual, and re-applied if the evidence still refuses

Limits

A removal reaches every later export and stops there.

Nothing maps a URL back to a file already handed on, and nothing propagates a removal into it. That work is unbuilt.

Release from quarantine is one decision.

There is no per-document verdict, no queue, and no two-person approval. The next re-check re-applies the quarantine if the evidence still refuses.

Request verification is undecided.

How to confirm a request comes from the site owner has not been settled.

Explicit permission

If you would rather it collected something

The permissive direction has to be as easy as the restrictive one. An explicit permission with a recognised licence at the well-known AI policy path is what reaches training allowed automatically. This site publishes its own: /.well-known/ai.json.
