There's a few ways to go about this, and some are beautiful.
One idea would be to create an entire network of fake professional personas, build social media presences for them, and eventually have them say something carefully crafted to both be perfectly defensible yet enough to draw the ire of the internet outrage machine. Then, have them be fake-fired much to the angry mob's satisfaction.
After this goes on for a while, conduct some data analysis, permanently naming and shaming everyone stupid enough to righteously attack and ruin the life of a fictitious persona.
The chilling effect is then reversed: engaging in vicious mob mentality against complete strangers might just earn them a higher ranking on the dumbass list.
