So, for years I've used Akismet spam protection on on all of my Umbraco sites (Contact forms - I get zero spam!), and today, I thought about integrating it with nopCommerce.
Works a treat :) I'm considering developing a plugin, so that it can be used on the contact form, reviews, blog/news comments, forum etc.
Or, if the team would like, I could do develop into the source, and do a full pull request?
