What is no mutual friends who sent you?

As an AI language model, I do not have access to your personal information such as your social media account and your contacts list. Therefore, I cannot provide you with any specific information about "no mutual friends who sent you" without more context. However, in general, if someone who is not a mutual friend sends you a message or a friend request on social media, it could mean that they found your profile through a search or through a common interest or a group that you both belong to. It is important to be cautious when connecting with strangers online and to verify their identity before sharing any personal information or accepting their request.
