Hello,

I use the form wizard pro on the contact us page of our site. Recently, someone has just sent very abusive emails repeatedly through the form despite the presence of the captcha and the ip address seems to be some opera mini proxy.

I contacted Opera and here is their response :

Thank you for contacting Opera Software's abuse department. The IP address referred to in your report is one of many used by Opera Mini, a mobile browsing service: <http://www.operamini.com/help/faq/> Opera Mini works as a web proxy for a large number of mobile users. All requests are sent through our network in such a way that it looks to the web servers that the users are coming from certain IP ranges, while in reality these networks are only used for transit. The true source IP of clients that connect through the Opera Mini service is announced in the HTTP header named X-Forwarded-For, which is included with every HTTP request. This header is the de facto standard for proxy servers. More information can be found here: <http://dev.opera.com/articles/view/opera-mini-request-headers/> <http://en.wikipedia.org/wiki/X-Forwarded-For> The X-Forwarded-For header will reveal which ISP the request originates from. However, since our users are mobile clients, we are unable to follow up abuse reports with the originating telecom operator. Doing so would ultimately require disclosure of protected private information, and would thus need to be pursued through formal legal channels. We can provide you with contact information to the appropriate instances upon your request. Have a nice day.

-- Kind regards,

Christer

Is it possible to provide an option to include the http headers so that we can track people who anonymously misuse the form?

Thanks.

Thank you for those tips Joe. They are helpful.
