prevent hotlinking

[abracad_1999]

I want to prevent other sites hotlinking to images on my site which
appears as the urls:
japan.twinisles.com
japandesu.com

I have added the following lines to.htacces
RewriteEngine On
RewriteCond %{HTTP_REFERER} ^http://(.+\.)?twinisles\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://(.+\.)?japandesu\.com/ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://(.+\.)?japan.twinisles\.com/ [NC]
RewriteRule .*\.(jpe?g|gif|bmp|png)$ - [F]


However when I test it on sites such as http://www.free-webhosts.com/hotlinking-checker.php
the images still appear.


What am I doing wrong?

You are permitting _only_ hotlinks. You need to negate the conditions (put
! before the pattern) and remove the ORs.

Since the site you mention is specifically designed to demonstrate
leeching, the people who developed it have probably planned for such a
trivial prophylaxis. Also, if you're serious about protecting your
site you should learn how to capture protcol level wiretaps and how to
understand them.
