Customimgcaptcha: spam combat 2.3.9

[Kisha Samson]

Many of the popular CAPTCHA systems fail, simply because they are popular, and thus become an obvious target to train against. However, custom image CAPTCHA can not suffer this same fate, since every forum can use unique image sets

• Upload multiple custom CAPTCHA images (customised for your site)
• Supports multiple answers per image
• The CAPTCHA images are displayed randomly
• For every custom image you upload, 320,000 different possible versions are available to be shown to the user, making a binary comparison harder for bots
• Stats on each Image: How Many Humans Passed It Vs How many Humans Failed it*
• Stats on each Image: How Many Bots Passed It Vs How many Bots Failed it*
• Default example images are provided (and should be deleted and replaced with your own custom set / a set provided to you)
• CustomImgCaptcha is available in all CAPTCHA areas (replacing QA CAPTCHA / ReCAPTCHA where applicable)
• The CAPTCHA images can not be linked to directly with the public uuid (the image uuid is deactivated after 24hrs)
• If you have good ideas / images for CAPTCHA, you can export the sets, then trade/sell them
• An import mechanism via the ACP is provided (SQL is not directly inserted, the values are exracted and XF DataWriter is safely used)
• Exported sets are compatible with phpMyAdmin (but this should not be needed, unless the set is very large, since the built-in import mechanim can upload your sets)
• CAPTCHA attempts (passed / failed) logs are recorded in the Admin Control Panel >> Tools - This can give you information more detailed information about your CAPTCHA set (such as the human answers when they fail the CAPTCHA)

*Note: Human / Bot stats requires FoolBotHoneyPot (to distinguish between Human / Bot). However, without FoolBotHoneyPot information about passed/failed attempts is still logged and available in the Admin Control Panel >> Tools > CustomImgCapthca Logs
