I gotta say, I haven't received any spam emails from our email forms on our demo at
www.photo.gallery/soda/ -
Sure, I receive an email once in a while "sdfsdg test test", but no spam, and our demo gallery has a lot of visitors. I don't want to argue with you, but it shouldn't be possible for a bot to send spam through a flash form ...
As it works in HTML, the bot simply reads the html code, finds the form, the scripts and the button, and sends away its spam. It can't do that with flash because there is no source to read, it can't identify any button or any form.
Perhaps you can send me a link to your gallery - I would like to check if the HTML form is strictly inaccessible.
Of course, there is an option where some spammers are actually human. I doubt very much that is your case though.
