The Unacceptable Images clause is a What To Look For? clause in the Detect Unacceptable Images content rule, which looks for unacceptable images, based on a user-specified threshold.
ImageLogic rates the acceptability of each image it scans by assigning it a score based on its content. Higher scores are considered to be less acceptable than lower scores. Images scoring higher than the threshold value you've set are considered unacceptable and the appropriate action (typically quarantine) is applied by the content rule.
To define the threshold in the Unacceptable Images clause:
- Beside the Unacceptable Images clause in the What To Look For? area of the content rule, click Click here to change these settings.
- Click the appropriate radio button to either:
- Use the default threshold of 46.
- Enter a threshold of (user-defined value between 1 and 100).
The ImageLogic threshold change only applies to this specific content rule.
- Click Save.
| Raising the threshold reduces the possibility of false positives, such as images containing flesh tones (but not full or partial nudity). Be aware that the default threshold value may change automatically during a system update, as the behavior of ImageLogic is refined. |

You are not able to add What To Look For? clauses to a content rule. You are not able to delete What To Look For? clauses from a content rule, either. If you would like to use a particular What To Look For? clause, you need to create a content rule which contains that clause, using a suitable content rule template. |
