I can only speak for myself, but I often feel a little conflicted when I get a call from a scammer.
On one hand, I obviously don't like being bothered, especially by people who I have every reason to believe have conned others out of a potentially life-changing amount of money.
But on the other hand, if they catch you on the right day, they can be pretty fun to mess with. And while there's some value in wasting their time while they're wasting yours, some folks have become good enough at pranking them that they can scare them off before the scammer even says anything.
And while one woman on TikTok didn't necessarily break the speed record for doing this, it's not hard to appreciate the stunt she did pull.
