No, it's not been proven. The link provided a day or two ago is to a click bait or some other nonsense type site that doesn't give accurate info. MM's short to their heart's delight. ClayTrader and his legion of doom often march right into a ticker with momentum and kill it dead in its tracks by shorting the shit out of it. ADTM got the shit shorted out of it plus nervous sellers and flippers galore. We truly do not know LAM's involvement here at this time. To say LAM is dumping an infinite amount of shares is just your guess. No one here knows that for sure.
