Since PluralKit proxies work by deleting and reposting messages through webhooks, some of Discord's standard moderation tools won't function.
Specifically, you can't kick or ban individual members of a system; all moderation actions have to be taken on the concrete Discord account.
## Identifying users
You can use PluralKit's lookup tools to connect a message to the sender account. This allows you to use standard moderation tools on that account (kicking, banning, using other moderation tools, etc).
### Querying messages
To look up which account's behind a given message (as well as other information), you can either:
- React to the message with the :question: emoji, which will DM you a message card
- Use the `pk;msg <message-link>` command with the message's link, which will reply with a message card *(this also works in PluralKit's DMs)*
An example of a message card is seen below:

A common rule on servers with PluralKit is to enforce system tags. System tags are a little snippet of text, a symbol, an emoji, etc, that's added to the webhook name of every message proxied by a system. A system tag will allow you to identify members that share a system at a glance.
You can enforce system tags for all PluralKit users in your server with the following command:
It's not possible to block specific PluralKit users. Discord webhooks don't count as 'real accounts', so there's no way to block them. PluralKit also can't control who gets to see a message, so there's also no way to implement user blocking on the bot's end. Sorry. :slightly_frowning_face:
