Every pro-league is going to end up doing this. Either through publicly visible time-delayed streams of the user's room, desk, front-of-user - or through a private entity dedicating a resource to manually review reports from proctored games who will only view suspicious or manually reported encounters/events. Obviously this doesn't scale, so it'll be limited to paid leagues and tournaments.
