no one likes getting spams. this blog has been getting lots of spams with non-sense messages until this plugin is installed. it can't prevent comments submitted manually and intentionally, but it prevents automated submissions.
i decided to develope this plugin since there isn't one available. well... there was one but it was for older versions of b2evo. i couldn't get it to work and now the link is broken. while i love b2evolution, its plugin directory is very outdated and it's frustrating you can't find anything up-to-dated.
please note that i haven't added this plugin to official plugin directory. it's not thoroughly tested and i need to tidy up codes.
this plugin simply adds a simple verification field to comment form. there are 2 types of verifications - alphanumeric text or simple 1-digit arithmetic calculation. comment will only be submitted if the correct random text is entered or the math calculation is answered correctly. both the text and math questions are generated randomly.
current version only adds the field to comment form. ideally it should applies to all forms. i will work on the other forms later.
logged in users will not see this field.
this plugin is developed in b2evo V4 but has also been tested in V5-alpha. however captcha / turing feature has been added in V5 so you have the option to use the built-in feature or this for V5.
not sure which one to use. basically it's free. you can do whatever you want with it.
it's greatly appreciated if you could link back to this post and contribute a small donation (tip jar at top right section of the site).
0.1 - initial beta release.
0.2 - simplify the random text and allows numeric answer to math question.
- download the plugin. untar.
- upload the folder to plugins directory.
- activate the plugin via plugins menu.
- in plugin settings, choose verification type. verification prefix is simply for a hidden field in the form for verification purpose.
please report any issues to the project page so i can easily keep track of any problems.
if you have used this plugin on your site, i'd love to see it! please leave your links and let me know what you think in the comments.
