20) **Shadow ban a user.**	

> Shadow-banning is a useful tool for moderating malicious or egregiously abusive users. A shadow-banned users receives successful responses to their client-server API requests, but the events are not propagated into rooms. This can be an effective tool as it (hopefully) takes longer for the user to realise they are being moderated before pivoting to another account.

> Shadow-banning a user should be used as a tool of last resort and may lead to confusing or broken behaviour for the client. A shadow-banned user will not receive any notification and it is generally more appropriate to ban or kick abusive users. A shadow-banned user will be unable to contact anyone on the server.

**Note:** All these commands utilize the Synapse API. Always exercise caution and ensure you have the necessary permissions when accessing and modifying user accounts.
