Stupid and pointless. I like some of the pranks I've seen about how a guy stands in front of a Ferrari and asks girls on the street out etc., and they say yes and he asks her to follow him along, goes to an old car and in the moment they see that he isn't rich and that they've just projected, they immediately walk away again. So there's at least a point to it. But if there's a completely different person showing up on a date? What's the point? I'd like it when it would reveal the female's hypocrisy and her biases and everything ... but if a completely different person shows up and autistically babbles something about "Chad", that rather makes him than her look bad.
A lot of low-status men still believe they are at least considered to be dangerous animals, while women rather see them like insects: creepy, disgusting and inconvenient, but not even something you'd get angry about or spend time thinking about. Just make them go away and die or work in the beehive. In that regard, these catfishing videos are more humiliating for the men than for the women - because women just stand up and quickly retreat from these sperging insects.
