You could just add a hook after the IP has been added to the table, so programmers like me could use a custom “Antispam_IP” table on an MSSQL database for example to load the saved IP and download any blocked IP loaded from other Wp-Amour instances.
For now I have created a php file that does this and runs every xx hours, because unfortunately I cannot use a hook. Of course I could manually insert it into the code, but when I do an update then I would forget to re-enter it 🙂 A good solution for now pending future developments from the wp-armour staff
