Hello I have a website that logs referrers using the code below

$ref = $_SERVER['HTTP_REFERER'];

On my site it shows the top websites that have been referering the most.

The problem I'm having is people are using the codes below to cheat the system.

<div style="width:0;height:0;"><img style="width:0;height:0;" src="http://example.com"></div>

and

<script type="text/javascript" src="http://www.example.com">

The problem is when people visit there site it treats it like the referred someone to my site. I have to manually block the websites. Is there a way to prevent people from doing this?


Thanks
