Recently we've had reports about spam being sent through the photographer contact forms on Airliners.net. Some sad person has written a script that sends a spam message through the form to a lot of photographers.
No more of that. Today we implemented the first captcha on Airliners.net (Completely Automated Public Turing test to tell Computers and Humans Apart) which will prevent any more automated spam messages to be sent through the interface. You can read more about captcha here
Please try sending a mail to yourself to test that everything still works as it should.
