302 redirect hijacking has been around a long time - I thought that Google had closed it off years ago. I was very surprised and disappointed to see this thread.
Normally I'd think the .org was the tld, but I'm thinking it's possible the part after the ? is a query and treated as literal characters. So a script on the domain.us would serve content (a page) based on the query string.
no doubt due to some form of a duplicate content penalty.
A lot of my articles have been scraped and republished on other sites numerous times. If I search for a long snippet of text from one of these articles (within quotation marks), the article on my site is always number 1, but usually many pages on other sites containing the re-published article are also listed. In other words, many pages with the same content (my original plus many of the copies) are indexed.
If you can't find your pages at all, anywhere, one possibility is that Google's algorithm "thinks" that you were involved in the scheme. Or I suppose that another possibility is that Google has killed that content totally because of the duplicity, although this seems unlikely to me.
