Former Navy SEAL John Allen, known as MrBallen on social media, gained popularity with a TikTok video about the Dyatlov Pass incident. He has since pivoted his focus from military content to mysterious and strange occurrences, posting short videos on TikTok and YouTube. His new podcast, "MrBallen Podcast: Strange, Dark & Mysterious Stories," premiered last week and has already reached the number one spot on Spotify's true crime podcast chart. The podcast features episodes ranging from 30 to 40 minutes and covers stories such as the 2002 case of murdered teen Rachel Burkheimer.
