Option to not submit certain fields for "self-learning"

Hi,

I recently used Mollom on political advocacy action, a tool to allow the members of my organization to send feedback to the FCC. This was done by allowing anonymous users to submit a node. Each node submitted triggered an email to be sent to the FCC with the user's information and text filled in. The body text was identical for most of these nodes, as my organization provided a default value for the body of the node, allowing users to replace or customize the text of their message.

It seems that many users had to fill out a captcha, which they reported to us they didn't enjoy. And I suspect that they had to fill out a captcha because real spammers were submitting the form with the default body, Mollom associated that content with spam, and after that legitimate users' submissions were read as spam. Could this be? Or is it not such a fast process?

So I'm wondering if there could be a feature where I could say "on the body field of content type X, don't submit this to Mollom for self-learning purposes." Any thoughts on this feature? Any other tips on using Mollom in this type of scenario?

Cheers,
Alex
