Private collaborative playlists please! – Spotify - Music and Podcasts Review

I have a using Spotify for years and absolutely love the platform. I have collaborative playlist with my husband and some friends, but lately I’ve had random people follow and add a bunch of songs to our personal shared playlists. I would like to keep them collaborative and also keep the random‘s out. ??????
