Probably a boring answer but I know my grandmother’s credit card information. I live with and help take care of her, so she doesn’t mind sharing it with me. Not like I’m planning to do anything nefarious, but I guess technically it could ruin her financially.
I mentioned before “spelunking” is something that is common amongst people I know, and some friends once caused a collapse because something overheated, damaging a huge source of pride.
But nobody on Lemmy will connect the dots, right? Right?
