Oh boy. I suggest you google a little bit before making accusations such as this one. DeviantART is a well known site, they definitely don't need to spam comment threads to get attention. And no, I'm not in any way affiliated with deviantART, apart from being an occasional visitor.

Oh yes, the HN hiring threads are really a great spamming location. We have to do this to promote our totally unknown site. :P

(You might be being sarcastic, but I don't quite get that vibe from the "please stop it".)
