What it does
This extension manages a blacklist of IP-addresses of fraudulent users.

Sometimes users purchase items with stolen credit cards and the store owner ends up shipping items to fraudsters. The original card owner may reverse the transaction. However, the store owner often won't be able to retrieve the already shipped items.

By putting the fraudulent user's IP-address into a blacklist future online purchases from the same user, even with different cards, will be marked with a warning message on the OpenCart admin backend's order page. This allows the store owner to proceed with caution, possibly not proceeding at all with the order fulfilment.


Requirements
This extension does not modify any OpenCart core files, instead it uses Event handlers.


Installation
Log into the OpenCart admin backend and then proceed as follows:

1. Extensions > Installer > Upload to upload this zip-file.
   
2. Extensions > Extensions > Anti-Fraud > Blacklist IP to install and enable this module, along with the IP-addresses of fraudulent users.
