Microsoft had released a much publicized MSN Search Update. However, the effects have not been as well publicized. MSNdude says;
"We rolled back the recent update, so we're back to the status quo ante. All of your complaints may be accurate but they shouldn't be any worse than they were a few days ago."
This is not the first time MSN has done a roll back. February 16 and February 18, 2006 clearly indicate MSN'S rollback records. Most of the members at a WebmasterWorld thread wouldn't even call the results spam, they called the results "irrelevant" time and time again. Types of problems included tons of subdomains (many blogs) that can fill the first page of results. Others noticed a huge weight increase in keywords of a domain name, hence the subdomain issue mentioned just before. Others noticed "footer pages", such as privacy policies, terms and conditions, copy-write pages and so on, ranking in the results.
