The trips that I lead are very different from the trips I do on my own. On led trips, I always use designated campgrounds and trails- no exceptions. I also never do anything in inclement weather. it's a way to get other college students out in the wild.
That being said, when it's just me and my experienced friends, we'll abide by the "as conditions warrant" principle, but only on rare occasions... stealth camping in Maine is a good example. Set up camp in the dark, no fire, gone at dawn- nobody's hurt, and nobody's the wiser. We're good at selecting spots where there wouldn't likely be a conflict if we were found.
I make my best campsites public, usually. I like to share my experiences. I also advocate for safe practices very publicly, so I can be a good example. I don't hesitate to call myself a role model; the occasional bent rule does not, I feel, influence this.
Plus, I don't want to lose context here; it's not like I'm spending time seeing how I can get away with things. 95% of the time, I'm perfectly within camping restrictions and I'm doing nothing to go against LNT practices anyways. It's just the odd time when we try something creative that I need to think about whether what we're doing is warranted.
