You seem to be trolling
Much as I enjoy winding people up, in this case no.
You give one fleeting (and incomplete) mention to the actions of FunnyJunk. Having done some more reading, it would appear that FJ is in the wrong, at that the Admin is just trying his luck.
But then, I guess the point of the article was to show that copyright users can always use the DMCA (even when they can't) so the actual circumstances were more of a substory than anything.
if I'd been trolling, I'd probably have said something more explicit and in keeping with the copyright mantra of big business, perhaps involving Oatmeal suing the users of FunnyJunk because it's obviously too hard to get the FJ Admin to comply.
In all seriousness, though, the DMCA is an American law which only has effect inside American jurisdiction. The FJ server is in the Netherlands, so it's highly unlikely the host would worry about the request. The admin of FJ quite clearly wouldn't have given a takedown any credence whatsoever.
It shouldn't matter whether a takedown is issued according to the DMCA or is simply a polite email saying "that's my work, and you don't have permission. Please take it down", a site Admin should respond the same way in either case. Not to mention that, if we want to be really picky, having received the latter the Admin is then aware of the infringement. Under the DMCA they become liable, so it's really in their interest to take the content down however they are notified.
For more constructive dialog, perhaps someone could enlighten me on the following;
0) Content goes up
1) CH notifies the admin, who takes it down (eventually)
2) New content goes up
Is there any element of 'due diligence' required? I.e. if you've had a complaint from a site, and it's easy to add a script to check for content from that site, is it expected that you at least take steps to try and prevent a repeat?
As much as sites like to blame the users (and to some extent it's their fault) in this case, the Admin of FJ has behaved pretty fucking poorly.
