The verb originates from the DeFlock website, which is a public mapping website that keeps track of the location of security cameras that monitor public areas, usually alongside roads, which monitor and record data while surveilling. The website's name comes from de- (“to remove, to excise”) + Flock, from the company Flock Safety, which is named idiomatically after a flock as there would be so many cameras in relatively close proximity to be similar to a flock.
