We are continuing to see more and more spam bots. Spammers are not letting up and are still actively researching and breaking “captchas”. We have seen several of them broken within the past few weeks. It seems it’s about time to adopt a new system of anti-bot measures for registration forms, or increase the complexity of the captcha (while also increasing user frustration).
That reminds me of a study I was reading about spam though. The researchers in this study found that only about 1 in 12.5 million spams result in a sale of whatever was being spammed about. However, even with this atrocious rate, the spammers are estimated to be generating around $7,000 a day!
