+The bot account `@moderation:hamburg.ccc.de` (Draupnir) maintains various internal lists of rules that are applied in so-called "Protected Rooms".
 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.
