As for syd's link, the dl leads to dA and a 404 (eventually).
The only reason it's there is that the author didn't know it was, or did and they didn't remove it on his request.
DMCA notice won't help, as only the author can file that and no one seems to know his location, and even were he to file one the site's compliance would be dubious as both are located outside the USA.
His intent, however is clear: He's gone from WC and gone from dA.
