1) someone other than the rights holder can request a takedown. They have to provide proof of delegation. All requests from a rights holder enter the same queue. They are not queued by delegated authority. If one delegated authority makes a bad request and does not pay then all other requests from that rights holder are queued. Make sure you delegate authority correctly and oversee their actions. Delegats acting wildly will cause a pain
2) All requests for take down must include a URL and quote of identifiable material found at that URL that can be matched with material claimed by the rights holder. The rights holder must provide cited title of the quoted material.
Respect is given to the rights of material creators and respect is given for the DMCA, but note that takedown actions causes a lot of work to make sure they are vaild. We can't afford to chase down false leads. If you provide a false lead you drop out of the time serviced and stay behind every other request that has not made a false request. If your request is not in the time serviced queue it will be in the resource queue which will be serviced after we have dealt with all items in the time service queue. If people keep giving us requests that go into the time serviced queue we may never get to the resource serviced queue.
Your request remains important to us but we only have limited resources and cannot afford to chase down false leads. Providing payment in recompense for the false lead will once again put your requests into the time serviced queue rather than the resource serviced queue. Payment provides us the resources to compensate for false leads.
Never provide a false lead and all your requests will be timely honoured.
