The JS file ‘custom_ajax_duplicate_alert_public.js’ is triggering an AJAX call to the server on the action ‘gd_duplicate_alert_action’ on every single ‘keyup’ event, which for a full “sign-up” form can amount to hundreds or even thousands of requests.
For example, the ‘Geodir Advanced Search Filters’ add-on bypasses this issue by making an AJAX request only if there were no keystrokes in the last 0.5 seconds.
This is a problem because some firewalls can identify this as a sort of DoS attack, and block users out.
