Proactive spam protection in backend with botscout.com API
There is an addtional option to add proactive spam protection in backend with botscout.com API for magento.You can choose not have the conventional captcha image and only have the invisible spam protection with this API.You need to register(its free ) in http://www.botscout.com/ and get their credentials to use this feature.My Personal suggestion is to use both image captcha (good for blocking bot posts) and botscout protection(for blocking human spam posts to an extend).
This is the first module I submitted to magento since I started working on magento customization .Unlike customizing other opensource CMSs ,customizing magento appeared more complex in the begining.But once I started more involved in it I started to love it .Gradually magento development became a thing of interest.I would like to thank those who wrote great tutorials about creating custom magento modules.My special thanks to fontis whose recaptcha extension helped me a lot to build this module.Infact this module is actually a forked version of their recaptcha extension.Below I have explained internals of this module including using AJAX in magento modules.Please go through if you are interested in the internals of this module.Those who want to customize magento will find this helpfull.I also hope this will be a good guide for any kind of magento customization.If you have any doubts regading customization of this module feel free to contact me through tha form below

Please install the module from magento connect before proceeding further.Please refer the following links and come back so that you can have a clear idea regarding the basics of module creation and AJAX integration in magento(if you haven’t t done this before)
I am not explaing the inner contents of each files since you will have the files added to your magento .Please note the naming conventions for each class and config nodes.By naming conventions I mean the usage of uppercase and lower case letters and underscores(_).For example a class name must contain the name of each folder in the path of that class from app/code/community folder,names of folders will be with first letter uppercase and remaining letters in lowercase.Each name should be sperated with an underscore. Custom modules will not work properly in magento without following naming conventions properly
