By meaningful real-world standards there are bot farms sowing dissent and literally driving people into mental illness which has already destroyed many families.

At the same time there's the Cambridge Analytica/SCL strand where a corporation literally sells election fixing services that rely on data gathered from social media accounts.

To be fair these are all extensions of political and media trends that already existed, and which online tech could amplify by some orders of magnitude.

Even so. The damage is very real.

One standard technique is to use attack bots to find a wedge issue and weaponise it by raising the temperature from both sides.

This can easily be automated now, so we're well past the point where literal humanity is the most important element.
