I have a website with two forms on it that allow users to complete and then download a Acrobat file. Lately we're getting a bunch of submissions that are random html codes and nonsense. We had this problem on a form with one of our other sites and once we added a image code verification feature to it the problem stopped. We would like to do the same for these other two forms to curb the problem. I would also like to have the form send the IP address of the user who completed it.
I will provide the links to these two forms as well as a example of our other site in the PMB to those I feel can do the job.
