We have a client running Foxycart and he's getting hammered with a lot of fake orders daily (some cases 600 or 700/day). He contacted his Payment Gateway (authorize.net) to modify the security settings which has helped a lot, but he's still getting a lot coming through every day which burns his time having to sort through real and fake orders. Once the product is shipped, the "customer" does a charge back and he loses his product and money.
Is there a way to add something like Google reCAPTCHA on the product page itself such that before anyone can even click on the "add to cart" button, they must first prove they're not a spambot?
By the way, I did find this posting in your forums, but it appears you didn't have a solution at that time:https://forum.foxycart.com/discussion/10694/recaptcha
