There is no proof needed, just look at the chart. If no one sold in large proportions, the stock would not be where it is today.
The fact remains is that the FLD concept was, is, and will forever be just a pipe dream. Even Monk himself discredited the FLD's power in his "official response" to the EIGH fiasco. There is as little proof of a FLD actually working as there is proof of major selling by den followers in the plays.
