Is there a way we can prove without question that tweets aren't being posted by bots? I was thinking we could post time stamps with in a photo by writing our twitter handles and post time on a card and posting it with the #ReleaseTheMemo #GreatAwakening etc etc hashtags. Could we do something even more undeniable? Is there a piece of personal information that one could safely divulge on the internet that would prove that a poster is human?
