Twitter Implements Duplicate Post Filter

Twitter recently implemented a new filter that prevents you from creating duplicate posts. TechCruch first reported it in their Cleaning Up the Stream; Twitter Kills Duplicate Tweets. It looks to be a 24 hour filter that will prevents the individual from reposting an exact copy of one of their previous Tweets. When this happens Twitter deletes the new message and displays a "Duplicate Text" message. However there is a loop hole that I found in that you can post from a third-party app, like TweetDeck, and then repost the exact same post through the Twitter site.
