Just read a story on BBC News about a guy that created a design firm on line, all meetings held over zoom, etc. Employees all around the world, making promises to sponsor people for migration visas sp they could come and work in the London office, etc.
One problem, a significant number of people on the calls didn't exist, they were using stolen pictures, stolen work testimonies (along with some wholly made up). Only came to light when someone got suspicious and checked the street address of the London office.
