Computer Help and Support

I think this is an overly-broad simplification of what this tool can do.

It tries to figure out if a photo is computer-generated or of a real person.

It does not attempt to detect if the user behind the profile is who they claim. When
catfishing the faker normally uses photos of a real people and then misrepresents
who they are.

So this is a tool that can sometimes show a profile is fake. But passing this test
is far from showing that a profile is real.

And ... I expect as computer generated photos will improve over time, the usefulness
of this tool will eventually evaporate.
