Code to prevent linking from specific site(s)

[amykhar]

I know this is possible because I have seen it done on a commercial site.

What I need is code to prevent somebody from linking to my board (any where on my board) from a given site. If somebody clicks on a link to my board from that site, they should get a custom error message that says something along the lines of "We do not welcome traffic from this site" or whatever.

Every once in a while, I get "freebied" by some of the major freebie boards. They descend and kill my server and I would like to shoo them off.

amy I guess the samples in this page might help to ban sites in .htaccess according to referrer info:

Thanks, Logician. I tested by blocking one of my own sites, and it worked. Hopefully, it will solve my problem

You can just play with the $url that gets defined in global.php.

I disallow guest access to my forums at peek times. But I have made an exception to allow people who visit my board from VB.org to come in at any time, and I display a welcome note at the top of the loaded page.

Click on my profile link and check it out.

How do you do that exactly?

In global.php:
Look for:

// check to see if server is too busy. this is checked at the end of session.php

And insert this right above it:

if(strstr($url, "http://www.vbulletin.org")) {
  // Insert code here...
}

I don't allow guests to view threads or messages at all. How would I make it so if I linked to something on my site from vb.org here, the link would show, but only for this site?

Ok, I have not tested this but here it goes.

change the if() statement from my previous post to this:

$vb_org = 0;
if(strstr($url, "http://www.vbulletin.org")) {
  $vb_org = 1;
}

In showthread.php there are 2 instances of the following code:

$getperms=getpermissions($thread['forumid'],-1,-1,$forum['parentlist']);

Insert the following code directly below both of them:

if($vb_org == 1) {
  $getperms['canview'] = 1;
}

This should allow a one time temporary view permission to VB.org visitors.

Thank you zzed.

You gave me the info I need to track what people are searching for at Google that makes them wind up at my site.

Instead of checking for vbulletin.org, I check for google. Then, I update a new table with the url. I use webtemplates to display the table to me and let me see what people were searching for. (the search term is in the url)
