I see three submissions of this post. This is the only one to get any discussion. All submissions were submitted by different people. All three submitters submit from a range of different sources.

Even this search shows a variety of submitters, with only a couple of substantial discussions.

But if you think there's something wrong with this article, or domain, or the people submitting it, you should probably email the mods.
