Alright les go

First you need to install http://statcounter.com/ on your blog. You make an account, and they give you a chunk of code to put at the top of your blog. (The best part is that you can have multiple “projects” or blogs under on account, perfect for sideblogs).

To create the code, go to this screen, type in your tumblr url, and click “invisible tracking”. To go to the next page just press the enter key. On the next page, select the installer for tumblr, and they’ll guide you the rest of the way. 

Now that you have installed a tracker, go to your project stats, and click the tab on the side that says “Recent Visitor Activity” You’ll see this page here, with all the people’s interactions on your blog. It only records 500 hits at a time.

Okay so now you have a place where you can access visitor’s IP addresses. 

The next step is to get a code that allows you to block and re-direct people whose IPs you’ve blocked. Here it is:

<script type=“text/javascript” src=“http://l2.io/ip.js?var=userip”></script>
<script language=“Javascript”>
function preloadFunc()
{
var ip = userip;
var bannedips=[
“00.00.00.000”,
“00.00.00.000”,
]

var handleips=bannedips.join(“|”)
handleips=new RegExp(handleips, “i”)

if (ip.search(handleips)!=-1){
window.location.replace(“REDIRECT PAGE HERE”);
document.write(’<!–’);
}
}
window.onpaint = preloadFunc();
</script>

Replace the 00.00.00.000 with the IP’s you want to block, make sure they’re in quotes and are followed by a comma. You can add as many of them as you want.

Next is to create a page they redirect to. You can NOT redirect someone to an outside page, like a different tumblr account or another website. Say you want to redirect someone to “yoururl.tumblr.com/banned” all you have to put in the quotes is “banned” because the “yoururl.tumblr.com” is already implied. You will need to make a page for the people to be redirected to.

This code also puts the user that you’ve banned into a load-loop, meaning the page, while still visible to the person, is refreshing at a rate of about 2-3 times a second. It depends on the browser they’re using, but a lot of times this rapid data use will slow down the browser, and crash it.

So what you do when you wanna block an IP, say someone sends you a nasty message. You can block the anon through the message, but that doesn’t stop them from looking at your blog. So here’s what you do:

1. Go to your statcounter page and click on the “Popular Pages” tab on the side (its near the top)

2. scroll until you see “yoururl.tumblr.com/ask” 

3. Click on the magnifier icon and it will show you visitors that have recently viewed this page.

Here’s where you need to do a little guess work. If you have the timestamp extension installed through xkit, all you need to do is line up the times. 

Disclaimer: Visits, and messages as well, sent to you over the mobile app do not show up here.

So when you have the IP, all you do is copy and paste it into your HTML, and you’re done.

Now, on to the harder part, finding your school’s IP. You really can’t do this without going to your school and recording your IP address while you’re there. And some schools can have more than one IP, depending on size. 

Another way to find your school’s IP is, if it’s a big school or university, it is sometimes online. I know MIT’s IPs are posted online. There are no services, that I know of, that do reverse IP lookups. 

I hope this helped!
