+### Deprecate `report_as` in challenge configuration
+
+Previously Anubis let you lie to users about the difficulty of a challenge to interfere with operators of malicious scrapers as a psychological attack:
+
+```yaml
+bots:
+  # Punish any bot with "bot" in the user-agent string
+  # This is known to have a high false-positive rate, use at your own risk
+  - name: generic-bot-catchall
+    user_agent_regex: (?i:bot|crawler)

+      difficulty: 16 # impossible
+      report_as: 4 # lie to the operator
+      algorithm: slow # intentionally waste CPU cycles and time
+```
+
+This has turned out to be a bad idea because it has caused massive user experience problems and has been removed. If you are using this setting, you will get a warning in your logs like this:
+
+```json

+  "msg": "use of deprecated report_as setting detected, please remove this from your policy file when possible",

+
+To remove this warning, remove this setting from your policy file.

-## Importing the default configuration
-
-If you want to base your configuration off of the default configuration, import `(data)/meta/default-config.yaml`:
-
-```yaml

-  - import: (data)/meta/default-config.yaml
-  # Write your rules here

-```yaml
-bots:

-  # Write your rules here

-
-These rules will allow traffic that "looks like" it's from a modern copy of Edge, Safari, Chrome, or Firefox. These rules used to be enabled by default, however user reports have suggested that AI scraper bots have adapted to conform to these rules to scrape without regard for the infrastructure they are attacking.
-
-Use these rules at your own risk.

 ## Importing from imports
 
 You can also import from an imported file in case you want to import an entire folder of rules at once.
