Question for the ladies

I have a friend that is a provider. Really a friend. Not a while knight. She received a text threaten to out her, including the address of her location and description of service she doesn't offer saying she did them. Immediately after she got the text she called the number. It was disconnected. Has this every happened to any of you. BTW she is not fs, that what he is threaten to tell everyone (her neighbors, and people in ajoining offices to her studio

If someone were to tell me something like that about a lady, I'd blow it off to a pissed off ex- boyfriend or jealous dude just trying to cause her trouble. All she has to do is ignore it.. it's a case of "he said- she said"..
