Not too sure, I wasn't actually paying attention for most of that IRyS stuff. If we can presume that those recordings are the same as the person I'm thinking of, she was at least somewhat 4chan-adjacent around 10 years ago, and recorded a lot of that kind of degen audio stuff, then had some kind of a regret moment a la Nyanners and wiped a bunch of it out and disappeared for a while. She ended up showing back up making similar stuff a few years ago on reddit. When I don't have better things to do I might try to dig around a little to see if I can figure out what her name was.
