Apparently, this same guy tweeted repeatedly that the Cubs had an agreement to trade for Hamels back in June 2015 and he just needed to waive his no trade clause. He eventually weaseled out of that claim by saying the Phillies changed their mind.
It was interesting how quickly and harshly Darvish and all Cubs beat writers responded. Most of the time, they barely even acknowledge a tweet like this from someone who just wants attention.
