Hi Mrugesh,

This might be a computer generated comments are posted to your website usually known as "spam bots", and there are various techniqes available to to check whether the poster is human or a computer like 1) Captcha and 2) Some alternate of Captcha etc. out of these Captcha is more popular and used frequently now a days to protect website from spamming.

The second thing you notice about the posts are that they all are from different IPs - and its possible to acquire different IP for a sigle machine for different post so they might come from one single machine.

I advise to make use of Captcha or filter information that are come from outside of programme before inserting or displaying them back to your website there are some function that take care about filtering user input like htmlspecialchars(), strip_tags() etc...

Hope this will help you to recover from the problem

The spam is coming from different IP address. So, i cannot able to
restrict it.
But your CAPTCHA suggestion is good. I will implement it.

But I think there is only one alternative CAPTCHA. Or other good
solutions is there.
I want to restrict spam in any case. I found some more information
that there are third party
services that restrict spams also.

And i am listing here that modules which restrict spam also.
http://drupal.org/project/mollom
http://drupal.org/project/spam --> Is this spam module satisfy our
requirement.

I dont know please reply...

Thank you once again. KM.
