Because of accessability issues this mod is no longer being updated. please use the Gatekeeper mod instead
This mod may help prevent bots (web robots) from doing the following on your forum;
1. Registering accounts automatically 2. Posting link spam automatically 3. Emailing your members automatically
It does this by asking the user to read an image and type the characters into a textfield. The characters are designed so that a computer cannot work out what they are. This is called a CAPTCHA test - Completely Automated Public Turing test to tell Computers and Humans Apart. For more information on Captcha's see - http://www.captcha.net/
There are four captcha patterns included in the form of sub's; Grid, Lines, Circles and drawCode. If you wish to write new captcha patterns you will find the code in captcha.asp. Please share any patterns you create, the more patterns included the harder it will be for robots to crack.
one word of warning, this kind of Captcha does not comply with usability standards as visually impaired or colour blind users may have difficulty reading the letters<
Agreed. I use visual and audio captchas by using this - http://www.lanapsoft.com/ - Its fairly easy to implement, its cheap but not free.
If you only enable the captcha on post_info.asp then visually impaired people should never encounter it as its only shown to users who are not logged in.
There is an application available ($199 retail) which automatically registers accounts and posts multiple messages. Its capable of automatically detecting whether the forum is phpBB, Invision Power Board or Snitz.<
Quick question, if I'm only going to use the CAPTCHA for registration can I leave out the edits in some of the other files not marked required?
If so, do I just modify config.asp, admin_config_features.asp, and register.asp? I'm thinking I might have to do inc_profile.asp too, but I'm not sure.<
If you're just using it for registration you can leave out post.asp post_info.asp and pop_mail.asp. You need to do inc_profile.asp. It would be best if you made all the changes required in all files. You can turn off the captcha on post.asp and pop_mail.asp in the admin area.<
It's just that I've seen many threads here about the "weight" of post.asp, I thought if I was never going to use it there, maybe I shouldn't add it there.
Great mod Podge, but I just installed it and I'm afraid I won't be able to use it.
Some of the images are way too hard to read. A lot of our members are of the older generation, and I gotta tell you, I'm relatively young with good eyes and had a lot of trouble reading a lot of them.
Also, there are no instructions on what to do with the letters, unless you happen to hover over the image. Non-computer savvy people (like our older generation) will certainly be confused. (just an observation, not a deciding factor, could be easily remedied)
If you happen to hover over the image, it says you can click to reload, but at least in IE, you get the "page has expired do you want to retry" message. When you retry, all the info you input is gone and has to be redone.
The Gatekeeper mod is probably better because it doesn't have the accessability issues. I need to update the zip for that mod with proper instructions though.<
I have installed it and after fixing all the buggy code I found it still doesn't work. If I enter a wrong number of characters and then enter the correct number, but all wrong letters, it'll let me send e-mail<
