Alert on NSFW Content

Contextal Platform's image processor includes capability to detect NSFW graphical content. We will create a scenario triggering an alert action when such images are detected in the data flow.

The base of our scenario will be the following ContexQL query, checking the value of $nsfw_verdict key in Image metadata:

object_type == "Image" &&
  @match_object_meta($nsfw_verdict == "Hentai")
  || @match_object_meta($nsfw_verdict == "Sexy")
  || @match_object_meta($nsfw_verdict == "Porn")

tip

Depending on your needs or the integration requirements, you may consider changing the action to BLOCK or QUARANTINE.
