# Blocklist

If you want to block a participant from participating in your panel/studies, you can now add them to the Blocklist. This will flag the participant in question, and prevent that participant from being messaged or completing screeners.

When a participant is added to the blocklist, you will notice this in two areas. The first is the Blocklist panel property:

![](/files/58c5c855cf4cc0312a391d0290df4d9519f2398f)

The second is on the panelist message tab:

![](/files/055dd6bf8b01b97258c1beb01e5d3cb79d324f5b)

Additionally, the panelist will not be notified that they are blocklisted. This is to prevent the panelist from knowing that their account cannot complete screeners.

If a panelist has incorrectly been assigned to the Blocklist, you can set the blocklist panel property to False, and the participant can complete screeners and be messaged as before.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.dscout.com/private-panels/panel-management/blocklist.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
