By doing this, she is able to live in the room for free and is said to be able to receive rewards from dubious real estate agencies or owners, whereas they would not have to report that the house has having issues in the past. According to a letter enclosed in a video, the woman accidentally learned about room laundering and managed to survive her financial struggles. She then became a "property gypsy," moving from one residence to another. One day, while shooting a video for a net idol-like YouTube channel that she had been running on her own, she captured something unbelievable in one of the accident sites. When her friend showed the video to an acquaintance in the television industry, they offered to pay her for the footage to use it in a paranormal TV show. With the considerable amount of money she received, she began filming more terrifying images and started her "accident site diary."
