Here's a good one for you.
I found one of EJ's (Escape on here) videos on Huffington Post a while back, so I told him about it and he went off on his adventure of asking for takedown.
Turns out it came from SportDiver, and they followed up with EJ:
We received the email below from AOL/Huffington Post regarding your video Phycocaris Simulans The Hairy Shrimp.
The video was originally provided by NAD to be used on Sport Diver's website. The video was tagged incorrectly in our content management system and ended up in our feed to AOL. The video has been removed from AOL, Huffington Post and from Sport Diver.
It just so happens that EJ and I were sat next to each other waiting to go diving, when the email came in, so here was the reply:
I'm diving with Simon (the owner of NAD) now.
Can you send me email about permission of usage my footage from NAD?
That's me on the left

A few days later and they still haven't provided the proof that I gave them the file. So i'm pretty pissed that they took a stab in the dark and suggested that I had been giving away his property. Besides, surely it has nothing to do with me anyway, as the movie was originally hosted by EJ and says 'by Eunjae Im' on it... George Clooney wouldn't put up with this sh*t, I don't see why EJ should have to

This 'take the easy way out and blame someone else' is pretty shocking. If EJ wasn't a close friend, it could have ruined my relationship with a client.
The purpose of this thread is not to discuss the original infringement, but as a warning for this method of diversion. As a message to all, when someone starts squirming about what they've done wrong, don't believe them even if they are a reputable company.
