# Block a user on behalf of a creator

`POST /creators/{creatorUserUuid}/blocks/{userUuid}`

Block a user on behalf of the specified creator.

**Blocking a fan auto-cancels their subscription.** When the blocked user is a subscriber, this endpoint cancels their active subscription to the creator (cancellation reason `creator_blocked`) as part of the block. It also marks the conversation with the blocked user as read. These are existing platform side effects of a block, applied here for parity with the Fanvue app.

Returns 404 if the target user does not exist.
