You can't ensure anything. The most you can do is look at the work and
consider what the most likely method of producing that work is. If the
author claims otherwise, you (and the ftpmasters) have to decide
whether you believe the author or not. [And frankly, if the author is
making PDFs insanely, using their software may not be particularly
useful, either.]

You'll note that I don't say anything about what you say the source
is. I talk about what the author *uses*. Since you're not the author,
and it's apparently obvious, even to you, that the PDFs came from tex
source, that's what we should assume.

I'm not sure that I follow you here.

The sheer ponderousness of the panel's opinion ... refutes its thesis
far more convincingly than anything I might say. The panel's labored
effort to smother the Second Amendment by sheer body weight has all
the grace of a sumo wrestler trying to kill a rattlesnake by sitting
on it--and is just as likely to succeed.
