You can configure limits based on how strict you want your form protection to be:

1. Go to PixelForm Shield > Rules & Settings.
2. Set your thresholds:
- Maximum submissions per minute (e.g. 3)
- Maximum submissions per hour (e.g. 10)
- Maximum submissions per day (e.g. 30)
3. Enter a custom block message to display to blocked users.
4. Save settings.

Any user attempting to submit forms exceeding these thresholds will be automatically blocked.
