Of course they can sue but only if the accusations are false otherwise it'd be a disaster.
I'm done wth these conspiracy theories of bad guys killing life saving cancer vaccines. These people all have suffering friends and family too. Sure they might do a quick hit story and take a nice short profit but than they'd take their foot off the neck and make money the other way. No, there's something very wrong here and it ain't unscrupulous short players. It's been way too long now. And there's scores of Woodford's out there just waiting to take advantage of a orchestrated short attack. I'd bet Phase Five is closer to the truth than you think.
Undoubtedly a NWBO shorty hit and run attack that Phase Five bs.
PhaseVResearch have no website. Their only presence is a defunct Twitter account with a paltry 456 'Followers'. The last post there was on April 26th 2016!!! The individual (AF?) who set this Twitter account up probably bought the followers on Fiver! And people took this individual's Twitter opinions seriously? WTH? Never seen a more blatant and pathetic example of a bash..unless we are talking about Fraudstain's column of course!
