TrueTwit is a service committed to making it easier to manage your Twitter followers without having to wade manually though spam users. TrueTwit attempts to validate your new followers to see if they are human as opposed to automated bots. We are hoping to help you more easily manage your follower list without giving up control.
TrueTwit is working on a system that will allow TrueTwit users to check for bots and spammers without using direct messages. We expect to have this system in place soon.
