It's unclear what the following four options might mean.
- Do not restrict the bot from finding new archives.
- Do not let the bot use archives found on wiki.
- Do not let the bot find new archives from archiving services.
- Only let other users add archives to the associated URLs.
How are they mutually exclusive? Are they meant to increase in severity/restriction, as they read? Which of these settings affect user-added archives? I can take a stab at a rephrase but I'm likely to be wrong without knowing more.
