These comments which contain an invitation in the form of links, hoping for visited links entered into the comments. to avoid these things, you need to enter a specific code into your blog template. Here's how the application works:

<script type='text/javascript'>//<![CDATA[ var spamlist=[ 'http://www.blogger.com/profile/xxxxx', /* url of the commenter */ 'http://nama_blog.blogspot.com/xxxxx', 'http://www.blogger.com/profile/xxxxx' /* last url does not need a comma */];for(var v=0; v<spamlist.length; v=v+1){ $("a[href='"+spamlist[v]+"']").each(function(){ $(this).closest(".comment-block").find(".comment-content") .replaceWith("<div class='comment-content' style='color:red'>You have been banned! Please leave this blog!</div>"),     $(this).replaceWith("<span style='color:red'>BANNED USER!</span>");

For those who use templates to hack commenting system, could use this code

<script type='text/javascript'>//<![CDATA[ var spamlist=[ 'http://www.blogger.com/profile/xxxxx', /* url of the commenter */ 'http://www.blogger.com/profile/xxxxx', 'http://www.blogger.com/profile/xxxxx' /* last url does not need a comma */];for(var v=0; v<spamlist.length; v=v+1){ $("a[href='"+spamlist[v]+"']").each(function(){ $(this).closest(".comment_inner").find(".comment_body") .replaceWith("<div class='.comment_body' style='color:red'>You have been banned! Please leave this blog!</div>"),     $(this).replaceWith("<span style='color:red'>BANNED USER!</span>"); })}//]]></script>

Replace highlighted URLs and texts with your taste. And save the template.
