When an Ip has been blocked, the page that shows that access has been blocked has a HTTP status code of 200.
It would be useful if it could render with a status code of 403 (Forbidden) - or at least make it optional which status code to return.
The plugin works extremely well, but I have observed some blocked bots blindly continuing to try load pages when each is redirected to the page that explains it has been blocked - they may perhaps detect a 403 status code and stop their attempts sooner.
