    Why should they? But be sure to use Open Source Projects like https://github.com/JustArchiNET/ArchiSteamFarm or https://github.com/JonasNilson/idle_master_extended so that no funny business happens due to your account due to shady idler programs. Idler programs simply mimic what you're doing and Steam doesn't care about you actually played the game or idled the time since Playtime is IR-reversible and the more you idle, the more you can't refund the game which suits them well.
