One new problem I see on Facebook these days are lots of images shared of false claims of people coming to attack/riot in neighborhoods... like really poorly doctored snapchat screenshots that wouldn't fool anyone under 40 but get proliferated everywhere by boomers.

There's now a massive line outside my local Home Depot with people standing in 90 degree heat trying to return plywood and OSB for looting and imaginary "ANTIFA caravan riots" that never came. Absolutely corrosive stuff to social order in its own right.
