Similar thing happened to me. I had a roommate who regularly needed a loan for rent. They eventually descended into drug use and chaos and we wanted them out of the house. They kept missing their supposed move-out dates, so I offered to cancel out their ~$5k in debt if they were out on a certain date.
Keep in mind I was unable to afford groceries many of these months.
In the end, they cleared out on that date and I never heard from them again. Even though we were quite close at one time.
Money well spent really.
