I guess your awfully busy, but I will leave the widget up for another day or two. I did place the form using short code in a page and it seems to work. Although after testing it in the form on the page it does allow more than one link go through.
1 link could go: http://url_link
2 the next then could be url_link without the http:// and it went through fine.
suchas: http://josephstory.org and josephstory.org and joseph.heavenboundministry.com would all go through and be sent.
I suppose spammers really don't care if there is http:// leading the url or not.
