A friend keeps saving our voice-chat disasters as clips and I hate being the content

There are six people in our gaming server, and one of them records most sessions so he can save good plays. Nobody objected when the clips were thirty seconds of an impossible shot or all of us failing the same jump. They stayed in the private channel, and being caught yelling at a digital ladder was part of the joke.

Over time, the clips changed. He started saving conversations that happened between matches: my friend practicing a presentation, someone complaining about a manager, me telling a story about a terrible first date. He edits the funniest line into a short video with captions and posts it back to the group.

Nothing has gone public. He has not included last names, workplaces, or faces. The problem is the feeling that any sentence can become a replayable object. I now hear myself speaking as if an invisible audience is present. I abandon stories halfway through. When someone says something personal, I wonder whether the recording is still running.

I asked him to stop clipping me outside gameplay. He said he would never share anything sensitive and pointed out that the voice channel displays a recording indicator. Technically, I can see it. In practice, it has been on for nearly every session for a year, so it reads like part of the furniture. He thinks joining while the indicator is visible is consent to being recorded. I think agreeing to session capture is not the same as agreeing to become a recurring character in edited jokes.

Last week he posted a clip of me mispronouncing a word while tired. It was harmless, and everyone laughed. I did too, then deleted my own message where I had said the joke was good because I realized I was trying to prove I was not difficult.

Do I need to leave whenever recording is on, or is it reasonable to ask for a group rule about what may be clipped? My preferred rule is gameplay by default, conversation only with permission from the people featured, and deletion without debate when someone asks. He says that would ruin spontaneity. I think spontaneity that depends on people forgetting they are recorded is not much of a defense. How would you raise this without making the entire server feel like a compliance meeting?
