 These can include, for example, user bans or entire server bans.
 Additionally, certain automatic monitoring measures (so-called "protections") apply in these rooms, which trigger a configured action if violated.
 For example, a user is not allowed to tag too many other users in a single message, as this is considered spam and results in a kick.

 There, individual actions can also be triggered through the bot as needed, such as redacting messages, kicking users from all or some channels, etc.

+Currently we operate **two policy lists**: One for internal bans like "Hausverbot" or similar and one for general misconduct like harassment and spam.

 ## Banning a User
 
 ```
-!draupnir ban user general <glob> <reason>
+!draupnir ban user <list> <glob> <reason>
 ```
 
+- `<list>` either `general` for general misconduct or `internal` for CCCHH-internal reasons
 - `<glob>` can be a user ID (e.g. `@example:matrix.org`) but also more sophisticated. Be careful when using actual glob syntax as whole servers can be banned even if just a single user is the intended target.
 - `<reason>` is technically optional but should always be supplied so that we know why a certain user was banned in retrospect. The bot supports parsing quotations so `"<reason>"` is usually what you want if more than one word is used.
 
 ## Banning a Server
 
 ```
-!draupnir ban server general <glob> <reason>
+!draupnir ban server <list> <glob> <reason>
 ```
 
+- `<list>` either `general` for general misconduct or `internal` for CCCHH-internal reasons
 - `<glob>` can be used to ban subdomains of a domain too, e.g. `*.example.com`. If used, an additional `--force` is required after the whole command.
 - `<reason>` should be supplied and supports quotation (`"<reason>") if more than one word is used
 - When a domain is banned, we usually also ban all subdomains too. This needs to be done in two separate commands.
