Logic persnickitiness: 'IFF' is not a more emphatic version of 'if'.
'IFF' means if and only if. In other words, you are saying that
it's dangerous if it's real, and it's real if it's dangerous.
Also, it's dangerous if you're expecting tor to hide... and
you're expecting tor to hide... if it's dangerous.
Pretty sure that's not what you meant.
But you're main point is well taken, subject to the limitation
that most people won't know exactly what their threat model should
be for any given behavior and it's best to be cautious.
