Someone just bought 16BTC worth of Metafees minutes ago. Almost 50% of the available supply has been bought, nice! 
The only person I see who did that seems to be monsterer himself, which I wouldn't call buying?
Are you referring to this? http://cryptofresh.com/b/1374992
Other than that I don't see any bigger movements in any of metaexchange's accounts
