I was recorded in the hotel and the other party sent me a multimedia message. Can I ignore him?

Don't reply to this person, and don't download or open anything they send. This is to avoid further threats and risks. The first step is to call the police immediately when you are recorded video and receive MMS. This will make the police aware of the threat you face and take necessary actions to protect your safety. It is very important to contact the hotel management and tell them what happened so that they can take appropriate measures to protect your privacy and safety.
