If you want tons of spam then use this addon. There will be no reCaptcha. The standard x-cart contact form has it all.
"I am sorry, but developers stated that the Advanced Contact Us form won't be integrated with the reCaptcha. It can be added only via custom integration. Let me know if you would like to get a quote estimation."
In my opinion, developers like this need to be removed if we want x-cart to stay clean.
