How to Block users From Visiting Your Blogger Blog

Some time you will notice that certain IP users are visiting and performing some unwanted ( spam ) activities. This can be tracked using a tracker placed in your website/blog. Then the noted IP can be used to block or literally ban users from visiting your blogger blog. This trick is Implemented using JavaScript and PHP.

Login into your Blogger Dashboard >Edit HTML
As I always say before attempting any tutorial or hack its wise to make a backup of your blogger template. So please download your blogger template.

Locate <head> in your blog template. And paste the following code just at the beginning of your blog’s <head> tag.

var banned_ip = new Array();

banned_ip[0] = ’85.142′;
banned_ip[1] = ’22.98.69.1′;
banned_ip[2] = ’22.98.69.146′;
banned_ip[3] = ’85.78′;

var mes_bi = “Your IP is banned so you cannot visit this website!”;

for(var i=0;i<banned_ip.length;i ) {
eval(‘var re = /^’ banned_ip[i] ‘/ ;’);
if (re.test(mc_user_ip))
{
document.write(‘<style type=”text/css”>’);
document.write(‘BODY{display:none;}’);
document.write(‘</style>’);
alert(mes_bi);
break;
}
}
//]]>
</script>

Replace the IP ranges from the above code with the IPs of the visitors you want to keep out of your blog. Example: If you want to block all IPs in the range ’11.22.XXX.XXX’, simply add “11.22″ as the IP number in the above code.

Note: if entering the above code into your template returns the following error: “XML error message: The content of elements must consist of well-formed character data or markup.”, use the code from this website (exactly as it is given) instead of the code given above.

I used the code to block the range, and she is still able to comment on my blog (she is a a psycho troll who now makes me moderate my comments.)
And when I enter the addresses into blogger, blogger automatically attaches an ampersand {&} and the number 39 before and after each address.

Cheth, you have no idea how much time you have saved me with this. I tested it with my own IP to see if it will work, and it did. I had used Toolator before, but for some reason, it no longer works on my page.

Once again, your work and help for bloggers is appreciated! Thanks!

I tried both codes which redirects visitors to your page. Your code seems not good-mannered.

Maybe you can get it's original source code from that page (http://code.vietwebguide.com/php/addr.php) and modified it, so i can place it on my desired host and redirect troll to my desired page, it helps me a lot in earlier time.

Your work and help for bloggers is appreciated! Thanks Cheth.

Hey Cheth, I tried the code. If I put it right after the -head- it redirects everyone but if I put it after the meta tags in the head is block no one and I did test my IP but it didn't work. Using the corrected code for xml keeps giving an xml error. Please help.

Don’t you also need to change the src= part to replace the website in this code with your own website? I tried to use the code as given and only replaced the IP but it messed up my blog entirely redirecting it to the website mentioned in src. Fixing it was a bigger pain because I had to somehow stop the browser before it redirected and then had to remove the code. Please confirm. If so, I request you to mention it in the instructions where you talk about replacing IP, to also replace the src website.
