This is (AFAIK) basically how Usenet piracy works. You send your warez to one provider, and that provider instantly replicates them to all the providers they peer with, recursively, until they eventually reach the entire network. When any of those providers get a DMCA complaint, they remove the offending files (as they're required to do by law), but they don't inform other providers that they've received a DMCA notice, so those providers keep serving those files. This makes it much harder to remove data from the network than it is to add it.
