I was trying for the last few months for some creative way to stop spam registration arising from certain countries, tried registration forms with captcha etc. But they still kept coming. Then I realized I can use Metamod and GeoIP function to stop users from specific countries being able to register. I wrote about my need in the forum and Stephen was immediately helpful within a few hrs I had my requirement fulfilled.
One should thank Stephen for this amazing Module. This module should rather be included in the core of Joomla considering the length and breadth of its applications. Truly the work of a genius. Hats Off Mate.
