I was going to mention that if you don’t mention names and they won’t be able to figure it out, it’s okay.
BUT, you have to be very careful with that (which is why I was reluctant to mention it). The Frum world is very small and often people can end up figuring out who you are talking about even if you don’t think they will. I definitely know of cases where that happened.
It’s also happened to me that someone told me a story about someone without saying the name, and then another time the same person told me the story again (having forgotten that they had already told it to me), but this time they said the name but said it with less details. They didn’t remember that they had already told me the story with more details so now I knew who it was about.
