Example:
TODO
Redactions
----------
Since events are extensible it is possible for malicious users and/or servers to add
keys that are, for example offensive or illegal. Since some events cannot be simply
deleted, e.g. membership events, we instead 'redact' events. This involves removing
all keys from an event that are not required by the protocol. This stripped down
event is thereafter returned anytime a client or remote server requests it.
Events that have been redacted include a ``redacted_because`` key whose value is the
event that caused it to be redacted, which may include a reason.
Redacting an event cannot be undone, allowing server owners to delete the offending
content from the databases.
Currently, only room admins can redact events by sending a ``m.room.redacted`` event,
but server admins also need to be able to redact events by a similar mechanism.
