1bu.com proxy was creating lot of mirror pages and this was a big menace for google and other search engines, it seems yahoo has banned 1bu.com from their index see what this poster says in webmasterworld.com.
http://search.yahoo.com/search?p=1bu.com&vs=www.1bu.com(they had tons of indexed pages last time I checked) this is amazing, Yahoo once again outdoes Google. First the fixed the 302 bug and now 1bu.com. I find it hard to believe that G doesn't know about this, either way they should know since the web has been buzzing for a while about this (

It's their job to find things like this out. Most likely they filed this on the same cabinet as the years-old 302 page hijacking problem. Kudos to Y! and another huge thumbs down to the new Microsoft, at least when it comes to security responses.
