Thank you for your amazing reply @julianhorack

To be honest we don't really know who is a bot and who is human any more, even here on Steemit. I wouldn't be surprised if there are more bots and bot writers than we imagine.

That's right. And unfortunately there are more and more bots over social media.

Something like this caused one of the biggest stock market crashes, perhaps in the 1980s, where algo bot traders reacted to other bot traders on the other side of America and caused each other to trigger a massive selloff, crashing the stock market, so this kind of thing can get really out of hand, before correcting

Wow, that's really interesting, I haven't known about this stock market crash in 1980s. But yes, such scenario is very likely in the social media are, so differencing the fake news will be virtually impossible.
