# Simple Prompt Moderation

Check whether input consists of any text from Deny list, and prevent being sent to LLM.

{% hint style="info" %}
NOTE: Each new line on the deny list will be its own operation. This can be good for accuracy, but will greatly increase the Chatflow execution time.\\

It is recommended you Deny items of a specific type per line.
{% endhint %}
