That is a nice captcha.. most of them are so hard for people to read that it discourages some people, and I am dealing with people who have brain tumors. What my form does is ask the simple question: is this brain tumor related. Defaults to no. If they don't change it to yes before submitting it, the message is not sent and they get a page saying the message did not go through because we only accept brain tumor related messages - and to go back and select "YES" for brain tumor related if it is brain tumor related. When I first did it I logged all of the submissions to see if I was blocking real ones. I had a lot of spam before adding that. A few people did submit a real question and get blocked by that feature, but I checked and all of them went back and fixed it. I no longer get the automated spams. About 90% of all submissions were spam before. Now about 1% - and they are done by actual people who would get by the captcha anyway.
