There are several steps you can take if a LiveJournal user is using your bandwidth without your authorization
If you simply do not wish for them to load an image or file, you have the option of renaming or deleting that file from your server. Alternatively, you can protect the file or directory so that it cannot be accessed. Servers running Apache have the ability to block images from being loaded from any domain. Instructions on how to configure your server to accomplish this are available at
http://www.livejournal.com/users/howto/30334.html.
If you cannot make these changes, or if would still like to use the images in your own journal, the Abuse Team may be able to help you. You should file a report, providing specific links to the location where your content is being loaded, so that they can take action. You should also provide a link to the original image, on your server, to assist the Abuse Team in locating the content.
If you discover the unauthorized bandwidth use by reviewing your server logs, it is very possible that your image is only loaded in one location. LiveJournal's "Friends page" aggregates several users' entries into one location. Referers of the form
http://www.livejournal.com/users/exampleusername/friends/ simply indicate that the user has viewed the entry of the person using your bandwidth. Similarly, referers such as
http://www.livejournal.com/users/exampleusername/ or
http://www.livejournal.com/users/exampleusername/?skip=40 often indicate that the content is in an entry. It is often not necessary to report these locations; you simply need to report the original entry in which the image was used.
When making a report, you should report the exact URL of the location where your image is being used. If the content is being used in the journal's layout, you can report the URL of the journal; likewise, if it is being used on the userinfo page, you can simply report the URL of that page. If it is in an entry, you will need to report the URL of that particular entry; you can do this by clicking on the comment links. In most journals, these are labeled as "Post Comment" and "Read Comments"; however, the user may have customized these links. The Abuse Team cannot act on unauthorized bandwidth use within an entry without links to that particular entry.
While a user who is contacted regarding unauthorized bandwidth use may remove the reference to your content, they might simply upload the content to another server and reference the files from there. If this occurs, and if you hold copyright to this content, you may be able to file a report of copyright infringement, under the provisions of the Digital Millennium Copyright Act (DMCA) of 1998.
