My grandfather stopped answering his landline telephone because of these scumbags. Kitboga is a youtuber who winds scammers up and wastes their time, and is pretty righteous https://www.youtube.com/watch?v=HNziOoXDBeg
There's a whole cottage industry of scam baiters. Harvey Dentt, Rinona Poison, Scambait Central, Lenny the robot (much less active of late), and quite a few others.
Many of them use voice filters to sound elderly, or to change genders. It seems like a lot of the scammers are getting frustrated, constantly trying to figure out if you're Kitboga, etc.
A vital service that is educating the public while providing rich entertainment.
