Hi Sorbing.
Thank you for your question. I’ll try to answer as clear as possible in details:
1. The basic CAPTCHA solution is already provided for free. wpDiscuz comes with free CAPTCHA which is not just a simple CAPTCHA, it’s boosted CAPTCHA and has double (image text + secure key) spam protection ability. We’ve already cared about a free and built in CAPTCHA solution.
2. wpDiscuz reCAPTCHA addon is not a simple solution to add reCAPTCHA on a Login form, Register form or on Contact Forms. Those kind of reCAPTCHA integration are very easy and those should be free. But this is not the same case. Adding reCAPTCHA on a dynamic comment system with AJAX form loading type and with live update functions is a huge work. The another big challenge is turning this most “device-screen-size-non-responsive” CAPTCHA solution to a “responsive” CAPTCHA on all device screens and dynamically changing reCAPTCHA on different width of comment forms/reply levels. I can say this is the one of the most hard feature we’ve ever developed for wpDiscuz.
3. If for some reason the reCAPTCHA is essential for your website and you can’t pay this price just contact us via support[at]gvectors.com email address, and we’ll send you discount coupon to get it with minimal price. We’re always open for that.
