Clipper payouts

Add view tracking to <my clipping or creator campaign platform>, so each payout is worked out from the views of the videos clippers submit.

When a clipper submits a link, fetch the video and store its author, publish date and views. Reject a link whose account isn't the clipper's, or that was published before <campaign start>. Then fetch every video in a live campaign again every <how often>, and store a dated reading each time.

Work out each clipper's payout from the views gained during the campaign at <rate>. Show them the readings it rests on, and hold back a video whose views jump in a way worth a look.

A video that comes back deleted or private stays at its last reading and is marked for review, and a view count that comes back null means unknown: never pay on it as if it were zero.
