A while back there was a concept for a captcha I liked, but it seemed to vanish. It was called something like "StupidFilter" and asked a free form question. If you answer the question correctly, you can then post data on the site. That doesn't seem complicated to me and if each site had their own unique set of questions it might be harder to make a generic bot to bypass it. The reason I like this method is that you can tailor it to the audience of your site. PC modding site? Have entry-level PC modding questions. Bots would have to become domain content aware. Not perfect, but I don't need perfect.
Asking the web developers on here, how difficult would it be to make something like that? Or does that already exist?
- _fs 6y agoOnce upon a time I hosted a very small phpBB with a couple hundred members and a few posts a day. We had domain specific questions for our captcha, and they cycled between 3-4 different questions. Within a month, the bots had been programmed to answer all the questions on our registration. Being obscure and domain specific did not help.
- LinuxBender 6y agoHow about domain specific pictures? "What is in the picture below?" The put a picture of a CPU heat-sink using the previous example And have many pictures to cycle through. Maybe change them up every couple months. Or number the pictures/questions and have the script use a different batch every week. You just need 52 batches and use ImageMagick to change the checksum and quality randomly. Then change them out once a year. I mean, they can update the bot every week, but there must be some really amazing reason to go through that effort if your site is attracting such people. I could see that happening to a gambling site, but probably not the average site.
