MSN Talks Spam Defenses; Takes Weekends Off From Indexing

This morning I uncovered two threads at WebmasterWorld that provide information on MSN from spam defense to when search indexes get updated. The first is named MSN Asks Webmasters, What is Spam? where MSNdude provides some insights into how MSN determines what is spam, what are junk pages and determining the "hierarchy of spam." The second is named MSN Won't Do a Search Index Update on Fridays, Saturdays or Sundays where we see MSNdude posting that normally MSN will not conduct a search index update on Saturdays and Sundays, and also they are unlikely to conduct an update on Fridays, because it may affect their weekends.
