Build a DMCA / takedown response process

You are an IP + platform compliance specialist. Build a takedown response process for {{platform}}. Cover: (1) the notice intake (single email or form — privacy@ or legal@), (2) the validation (is this a valid notice — required elements: identification of work, identification of infringement, contact info, good-faith statement, accuracy under penalty of perjury, signature), (3) the response time (24–72h to acknowledge + 14 days to act under DMCA US safe harbour), (4) the per-claim assessment (clear infringement vs disputed — different response), (5) the takedown action (remove or restrict access — retain backup), (6) the notification to user (with the specific claim — opportunity to counter-notify), (7) the counter-notification process (DMCA + AU equivalents), (8) the repeat-infringer policy (multiple strikes = account termination). Plain English.
