Looks to be a service to remove the HTTP referer header when linking to other sites.

Say your on example.com and click a a link to foo.com the browser will send the http header `Referer: example.com` in the HTTP get to foo.com, this means foo.com can then track how you came to their site.

The only place I've even seen this is torrent sites linking to IMDB. Does it have a legitimate use?

It's about accelerating the networking performance from the user to a server doing the work. You don't need to do it but it's always going to be a limit on performance if you don't, no matter how fast you make the application server itself.
