Leads on who it is

any of these people may own a tape, or be muse_my_collection.

They may also be Educational_Habit_73 on reddit, considering he is also french, and had bought a Plug in Baby Maverick demo in 2026, and didn't release the audio. He said things under a post like "You wanted the audio files, you should have won the auction." (in relation to the plug in baby cd) "You're not a collector, so you can't understand, without meaning to be disrespectful. This cassette isn't just legendary for us; we want it to retain its air of mystery. Yes, it's frustrating, I understand, but life is full of unfair things, and this cassette is one of them. If you had my copy, I would die with it, without anyone hearing it except for very, very close collector friends who deserve it and have the right to know it. I have a lot of respect for them, and I want to share this legendary piece of music only with them." and "You don't realize who Benjamin is, seriously, respect the idea that the audios won't be released for several obvious reasons, and also personal ones. I think you can understand that, at least I hope so."

these messages also point to a person named Benjamin owning a tape.

another person who may have a copy is Graphically-official on reddit, for acting in a similar way under the same post. Saying things like "Of course he hasn't them but he's willing to fake it if they will ever be released. We collectioners have to feel safe of what is in our possess when it comes to this🙌" "Too bad. We ain't gonna share anyways, we're assholes as you said, right?" "I think I can for the fact that I am a collector myself🙃" and "It's not my fault if the reddit community cannot reach a bit of money for doing that, I've given the chance but it was thrown away🙂" 

also on their profile, their description says "I'm a full-time Muser, I usually draw something for them on IG✒️ - Happy to own one of the biggest Muse collection worldwide🔱"
