Undetweetable is perfect for your inner voyeur.
After you add someone’s Twitter handle to Undetweetable’s database, the service will catch any tweet before it’s deleted and display it on a Twitter-like interface.
Because it’s attracting a lot of attention and getting a lot of traffic, it’s not working properly at the moment. But you can still browse the deleted tweets of random users from Kim Kardashian to Fox News.
Once it’s back in working order, you can add your friends’ Twitter handles to the database to start tracking the tweets that they never meant for you to read.
