social shaming 

The use of social media to shame a stubborn or unresponsive company into fixing its goods or services. In short, it's applying the doctrine of public humiliation to shape behavior to social media and thus a much larger or at least potentially much larger audience.

I'm using social shaming to make a software provider fix its crappy software.

Social Shaming 

Calling out people on social media when they post pics of themselves standing with people closer that 6 feet other than immediate family/SO.

I was Social Shaming a buddy on FB this weekend over his reckless pics posted of multiple social gatherings instead of social distancing.
