 Again after the 2016 election there's been a lot of attention paid to the possible effect bots played on spread of misinformation and I think this is my personal take that is being exaggerated and I think this work somewhat points to that and I think our attention is being focused on something that might not be as big of a problem as people think it is. Or at least the problem and the situation is more complicated and looking for the problem when there's actually a complex of problems is the right way to think about it.
