I have added this module in Magento 1.9 for stop spam in newsletters.
This worked fine but, when I try to sign up for the newsletter via curl it works and it should not. It works on a lot of sites under Magento 1.9
curl -vvv -X POST -d "email@example.com" https://www.mysite/newsletter/subscriber/new
How can I block curl requests for newsletter subscriptions?
