redirecting a fusker hotlink 'attack' to someone else innocent is almost as bad as the original problem.
Hand them an image that advertises your site, redirect them to another fusker search url, or, do the right thing and track down their connections, report a DMCA violation to their host and both upstreams, then, take a look at the advertisers on that page, check their Terms & Conditions and write them an email saying that this advertiser is violating their T&C, take out the paragraph from their T&C and highlight it, and, send them links to content that you know they don't hold the copyright to.
Until you hit their money source, they'll never stop.
Here's a thread that includes a copy of the email I was sending to program owners. I believe it was somewhat instrumental in getting usefulidiot.com shut down which was a fusker clone.
So, if every time you see a violation it is reported to the host & the host's upstream providers and the fusker mirror's income stream, eventually it'll become a paid hobby rather than an income producing hobby and perhaps it'll lose its lustre to those running the sites. Either that or they'll get tired of continually having to find new sponsors.
