I frequently mark drawing NTS. While we attempt to draw our details to
scale. We sometimes have to exaggerate an area for clarity. Also I see no
reason to try and draw hay bales to scale.
We mark the details NTS to make it clear that only the dimensions called for
on the detail should be used. If someone is scaling from our detail. They
either don't understand what they are doing or else we have made an error in
dimensioning. Either way they should contact us for clarification.
Now. Lets discuss the plans we issue at a scale of 1" = 1 Rod.

Next... find the user that created the NTS drawing, and then smack them
upside the head!
Basically, I have seen our Electrical and Mech. departments take drawings by other disciplines and scale them down in order to fit them on a drawing sheet (whether it be a Floor Plan, Civil Plan, Structural Plan, and/or details).
Many a time I had to rap people on the knuckles (ie "smack 'em upside the head") for messing with drawings.
It took a couple of projects, but I have managed to get the Elect. and Mech. Depts. to: a)use XREFs, b)keep drawings (ours and theirs) full-size 1:1 c)and leave the orientation alone so that we can ALL use each others drawings as XREF Overlays with the same basepoint. They now appreciate the new approach when they discover situations like "I can't place my HVAC diffuser there because a light fixture is in the way" which has saved much embarassment and "Site Instruction" sketches.
