For a while I grew quite fond of wasting phone scammers time. I’d pick up, talk suuuuuuper slowly— like Emo Phillips speed at one syllable every one or two seconds— interrupt with irrelevant questions or anecdotes, and overall just see how long I could keep them on the phone without giving them any information. The best strategy I found was telling them that, yes indeed I did remember owing the IRS or whoever money and I could pay them however and insisting that first they needed to take down my new email address… I’d just start spelling random words incredibly slowly, say I messed up and start over, ask if they needed my checking account number to keep them engaged and then start spelling my email address again. They prey on intellectually disabled folks so pantomiming a stereotypical version of that wastes a ton of time while keeping their interest. Got boring after a while but I got pretty good at it.
