JoJo posted a thread at our forums named MSN "judging" websites manually? and at DigitalPoint forums named http://64.4.8.28/hrsv3/Judging.aspx in ref logs ? revealing a page at MSN Search named HRS at http://mshrs.search.msn-int.com/hrsv3/Login.aspx, which has the logo at the top, shown below.
Does anyone have the password? I am guessing, wild guess, no evidence, that HRS stands for "Human Review System" but I can be totally wrong. I did a search on msn hrs and found only non-english pages, here is one translated.
We know Google has human reviews and so does Yahoo, who doesn't. So one can assume that MSN does as well.
