Okay, so with any of those uberpopular artists, there's naturally a ton of sycophants. They're pretty annoying to watch as they praise nearly anything the artist will do, irregardless of quality or other factors.
But just as annoying are the Internet Policemen who like to inform the artist (using this term as loosely as an art history professor OH BURN) that they're is shallow, talentless, violating DA policy, even harangue other commenters, etc.
Jesus, it's the internet. It's DeviantART, at that.
