Every notice is judged as of the day it arrived: whether an agent was designated that day, whether it named the work, the material and a way to reach the sender, and what was done about it and when. Typed or pasted in by you. Nothing here goes and looks at anything.
When a counter-notice arrives the material goes back not less than ten, nor more than fourteen, business days after you received it — unless the complainant tells your agent first that they have gone to court. The ten days are the complainant's. The program counts them on the calendar you keep, and will not record a restoration inside them.
The safe harbour asks for a repeat-infringer policy that is adopted and reasonably implemented. Having one is the easy half. The finding that costs platforms the harbour is an account that crossed the line and was left open with nothing written down about why.
