What part of "secretly taken and deprived access to the outside world and denied their civil rights for days where the authorities refuse to admit the person is in custody" doesn't describe "disappeared"? I'll give you that in the past it's been used to describe death camps for dissidents in e.g. Latin America but the word is more general than that. We're still allowed to call e.g. waterboarding torture even if teeth are not ripped out and fingernails are not pulled off.
