Politwoops -- a database of tweets US lawmakers would rather you forget -- has been banished by Twitter for violating its terms of service. The Sunlight Foundation, which created the site (and still operates an EU version) recently tweeted that "Twitter (has)... decided to kill Politwoops. We're sad we're losing this public record of deleted tweets." The site has been tracking politicians since 2012, and occasionally surfaced controversial messages and images that were later retracted. Despite that, many political figures actually praised the site for bringing greater transparency to Washington.
