I love your insight on this "hidden" problem and to be honest I never really thought about until you brought it up.
I admit, I am one of those people who only look on the front page for my entertainment, but that is only because I never really have the time to investigate backstage for those rare goodies.
Once in a while, some stupid animation makes it onto the front page and I think to myself "What the hell?". But i have noticed that everything these days is about getting that quick laugh or acquiring that 15 minute fame or even trying to get attention through trolling.

I found that quote on a wallpaper with a picture of Boxxy from Youtube.
Sooner or later, the world will fall apart because of the internet.

I haven't written a lot of reviews lately, but I've found that when I stick to criticizing the work itself and stay away from the personal attacks the reviews stick.
I've been pleased with how quickly some abusive reviews have been axed from some of my submissions. On others the abusive ones seem to stay forever, so I wonder how the "threat level" of reviews escalates to a point of showing on a mod's radar.
There is probably room for improvement in the NG system, and I really like the idea of a "seasoned" classification for reviews where hand-picked reviewers get to assign a score. One thing I would like to see improved is the managing of "alt" accounts, or fresh accounts leaving reviews, cuz I've seen users, disgruntled by an author's response, create a bunch of alts, or pull up an army of old alts (or get a bunch of their friends together) and then spam bad reviews all at once...there's got to be some way to compare IP addresses or SOMETHING, even in this day of AOL ha ha.
That said, comparing NG reviews with other sites, NG provides a really well set-up system. From day one I've appreciated the blunt and harsh feedback NG has given my stuff, it's only served to help me improve, and I love the fact that the artist always has the last word.
For some reason, here the reviews, notwithstanding the smattering of lame ones, seem to be more well-thought-out and sincere and I value the feedback in a way no other flash site compares with...really, I view the review system on NG as one of the greatest strengths of the site.

I agree in that those who REALLY like an artist's work get a wonderful forum to express their appreciation. Those who don't like someone's work? Well, they have to tread carefully when offering their criticism, and that kind of biased and censored response is really not what I'm interested in as a developer.
