Actually, I'm not talking about spam or bogus files so much as just search results that seem to be generated regardless of your search criteria. Like I search for "*****, at 128Kbps" and I get a bunch of automatic results such as Tom Petty songs, Tim McGraw, and so on .... then once the search takes a few minutes, I get my actual results.
Maybe we're talking about one in the same issues here, but I thought this was different then the link you posted.
