the reason Captcha's are image based is that it is much harder for something to grab an image and work out what characters it contains -text based captchas are trivial to crack as the spammer can simply read the text and generate the result - it is much much easier to do that than to crack an image. As DNN is opensource, any rule based captchas that use text can be rapidly replicated into a spam robot - at best they would offer a small window during which spammers would have to update their scripts. After their scripts were updated then they would be able to crack 100% based on text challenges - this is why we are not interested in adding them (no matter how much you protest or score us poorly on codeplex)
Dear Cathal
It will good if all of users get 5 star for your job. If I was in your place I like it. but you need some big changes to rich to more success and some people like me that get 1-4 star and they talking about problems and troubles, we are cause for DNN growing because we let you know bugs and you can focus to fix in next issue.
But when you will several request about somethings like this (Spam registration) it means this is very important trouble and should be fix in next issue. Just It, Done.
If you don't like get any critique, It's Ok. We don't tell DNN any thing more. I like DNN. I grow with dnn in pas 6 years and I appreciate it. I want DNN be better and this is my target. I'm not your staff but I think I'm DNN staff because if DNN Grow and be come best CMS around the world, I got my target and success.
I'm sorry for my Criticism and I just hope this BIG CHALLENGE (Spam Registration) be fix for ever as soon as possible.
Finally I Advise DNN for all of my clients as you see in my main website (http://website.ecb.ir - It's Farsi and should be translate with google chrome browser to English) and you can see I compare DNN with other CMS because I want to show people what is DNN Power.... but I want get good result when I ask something and I want be share in DNN growing dear cathal.
Thank you again for DNN
