Exactly what these guys said. It's not that we hate SteamDeck users or anything, It's that somebody on a steam deck decided to try and hack. Steam deck's it turns out have near identical hardware identifiers. So anybody else who tries to use one outside of LAN mode will been seen by the anticheat as having made an alt account to bypass their ban and thus are re-banned.
Basically - cheaters fault for ruining it for everyone. Valve has some fault too, it's idiotic to release hardware that matches every single other bit of hardware.
Our warning on your thread was an attempt to avoid people accidentally getting themselves banned.
Edit: And to answer the inevitable question, no we will no re-write our entire anticheat just so a small section of gamers can use a steamdeck to play Plutonium. It's not an officially supported platform by us.
