Closes #30 Introduces the "challenge" field in bot rule definitions: ```json { "name": "generic-bot-catchall", "user_agent_regex": "(?i:bot|crawler)", "action": "CHALLENGE", "challenge": { "difficulty": 16, "report_as": 4, "algorithm": "slow" } } ``` This makes Anubis return a challenge page for every user agent with "bot" or "crawler" in it (case-insensitively) with difficulty 16 using the old "slow" algorithm but reporting in the client as difficulty 4. This is useful when you want to make certain clients in particular suffer. Additional validation and testing logic has been added to make sure that users do not define "impossible" challenge settings. If no algorithm is specified, Anubis defaults to the "fast" algorithm.

[Unreleased]
-
Administrators can now define artificially hard challenges using the "slow" algorithm:
{ "name": "generic-bot-catchall", "user_agent_regex": "(?i:bot|crawler)", "action": "CHALLENGE", "challenge": { "difficulty": 16, "report_as": 4, "algorithm": "slow" } }This allows administrators to cause particularly malicious clients to use unreasonable amounts of CPU. The UI will also lie to the client about the difficulty.
