 Once `SimplePolicy` is enabled, you can configure various groups in the `:mrf_simple` config object. These groups are:
 
-* `media_removal`: Servers in this group will have media stripped from incoming messages.
-* `media_nsfw`: Servers in this group will have the #nsfw tag and sensitive setting injected into incoming messages which contain media.
 * `reject`: Servers in this group will have their messages rejected.
-* `federated_timeline_removal`: Servers in this group will have their messages unlisted from the public timelines by flipping the `to` and `cc` fields.
+* `accept`: If not empty, only messages from these instances will be accepted (whitelist federation).
+* `media_nsfw`: Servers in this group will have the #nsfw tag and sensitive setting injected into incoming messages which contain media.
+* `media_removal`: Servers in this group will have media stripped from incoming messages.
+* `avatar_removal`: Avatars from these servers will be stripped from incoming messages.
+* `banner_removal`: Banner images from these servers will be stripped from incoming messages.
 * `report_removal`: Servers in this group will have their reports (flags) rejected.
+* `federated_timeline_removal`: Servers in this group will have their messages unlisted from the public timelines by flipping the `to` and `cc` fields.
+* `reject_deletes`: Deletion requests will be rejected from these servers.
 
 Servers should be configured as lists.
