I don’t have a clue, but I do find this fascinating. I came across you asking this question by googling it (I did come across a website traffic analysis form, that has been of no assistance) and came up blank. What I have found, as a recent trend of many high bandwidth websites, even free ones, that the internet appears to become more privatized. Examples of this has got to be like gmail.com, demonoid.com, or myfreepaysite.com, where it’s either email confirmation only, or by recommendation only. Another explanation could quite possibly be is that this link is just a “slave” link, where the actual site is exclusive to those that can track it down, and the link basically serves for the links they put on the site (I’ve seen lj-toys.com linked to videogum.com somehow)
