Discourse.net's problems with Google have worsened. First page rank went to one (from seven). Then it went to zero. Now it goes to a “question mark” which means that Google thinks something is wrong with the site.
Google webmaster tools says things are basically fine. Similarly, searching Google itself for “discourse.net” doesn't reveal the signs of a hacked site. There isn't some pile of sp*m showing up as far as I can tell. But there isn't much discourse.net showing up either — lots of things seem to have been removed.
Does anyone have a clue as to what might be going on or what if anything I can do about it?
