It's a different kind of scare tactic. Designed to create an environment of hesitation and shame, to make our peers censor us. "I heard about what you did last night." "Don't do that, we'll all get in trouble!" "Behave yourself, or everyone will know about it." Like children made to sit in a corner and face the ridicule of their peers. [pathetic and half-hearted scare tactics, to boot]
Probably Acumen assumes we won't obey any other way, since it doesn't expect its prisoners to be cooperative.
