Being one who has uploaded a troll deck on NRDB, I'm not going to try to justifying my actions. However, I want to explain that even troll decks serve a purpose. Sure, they're fun for some. But they also illustrate a point. There are a lot of decks claiming to be Tier 1 or very good or doing incredibly unique things when they really are just bad decks or worse copies of existing archetypes claiming to be incredibly good.
We did this thing where we tried to push a terrible deck to the front page, illustrating how easily one can mess with the NRDB front-page system. Alsciende, even though I love your work and I think that you've done a massive job (and I use NRDB almost every day), I think it's right to point out to the flaws. Now, I do agree that posting bad decks too often just kind-of defeats the main idea of NRDB, however, I think sarcastic works like these help raise the attention towards the issue.
