I know that internal policy has many, many, many holes after seating though those seminars, I am not an expert, but have enough knowledge to feel I was targeted, and with that I have to go look at policy documents and write a piece about a silly phenomena I am seeing with partisans. Suffice it to say, the last week on DU has been horrific personally. Starting last Saturday to be specific. So forgive me if I feel I have a very large target on my back.
That "internal policy" are part of DU's TOS. Many sites have similar policies, and members agree to abide by the TOS as a condition of membership. The exact phrasing varies from site to site - 4 paragraphs, 150 words - but if too imprecise for the journalistic world (ignoring the fact that having a few thousand $$ worth of photographic and video equipment and a few seminars doesn't transmogrify nads' hobby into professional journalism), those phrasings are simple enough for ordinary people to understand and follow, and close enough to accurate to ward off lawsuits if there is effort to enforce the terms.
If any DU-member thinks for a second, nads' gnat-straining argument to justify utterly ignoring fair usage should seem as ludicrous as it is. And "... after seating though those seminars ..." is rated

. Maybe nads should have invested in basic English vocabulary and grammar seminars instead of copyright seminars.
