# Block prospects' sites

`POST /v3/outreach/prospects/block`

Remove one or more prospects and stop them ever coming back from discovery. Use this for sites the user does not want to be associated with; to merely deprioritise one, leave it alone instead. An ordinary site is blocked by domain, so `removed` can exceed the number of ids you sent when it has several rows. A prospect on a creator platform (a YouTube channel, a Substack) blocks only that creator, leaving the rest of the platform discoverable.

## Request body

- object
  - `prospectIds` string[], required — Prospect IDs to block.
  - `reason` string — Why they were blocked, shown in the blocked list.

## Response `200`
