My website is receiving too many spam comments, what I do? I have installed a plugin but I'm not satisfied with it. How to block spam comments and spam users etc.
Assuming the spam comments are to blog posts or similar...configure a CAPTCHA so that a successful response to the challenge is required prior to a comment being posted or a contact form being submitted. It should reduce the number of automated responses.
CAPTCHA modules are available for most web software packages.
More about CAPTCHAs here.
CAPTCHA alone you cannot deal with SPAM comments as most of them are done manually.
- Using CAPTCHA : You can filter auto automated / bot comments.
- Manual Comments : Most of the SPAM comments are done to create back-links to their blogs. So, first of all just remove functionality of link to commenter's website from your website. So, just didn't ask for user's website and don't provide link back to user's website.
- Disallow HTML comments : So, now just make rendering of comments as text instead of HTMl so, that user can't post links in comments pannel.
So, now as you are no longer useful for them .. You can see considerable amount of reduce in SPAM comments.
