TweetBlocker

TweetBlocker helps in identifying the spammers in your followers. It’s very simple, just provide a twitter username and TweetBlocker will check its tweets and rank the user with a grade from A to F. Or you can login and it will check all your followers for spam tweets.

The application is pretty similar to TwitBlock app. The big advantage of using TweetBlocker is its ranking for the twitter users (A to F) rather than saying a twitter account is a spam or not as TwitBlock (which is not accurate all the time).

Greet tool to block spam accounts.
