The Auto Blocking Rules settings
The Block Bad IPs/Visitors module's main part is the Automatic IP Black List system (engine). It tracks bad behavior over a set period of time and as soon as it reaches the threshold, the Shield blocks it. No more lengthy and unmaintainable IP black lists.
To set-up the Automatic IP Black List system, use the following options:
- Transgression Limit - Visitor IP address will be Black Listed after X bad actions on your site
- Auto Block Expiration - After 1 "X" a black listed IP will be removed from the black list
