Twitter Cleanup: Use TweetBlocker
Spam is even worse when it follows you to social networking sites like Twitter. I honestly don’t get the benefit of having a Twitter account unless you’re really going to use it. A new site called Tweet Blocker shows all your Twitter followers and grades them using an algorithm based on the content of tweets.
A+ being the best and F being the worst, it is easy to identify who you can block or unfollow them (if you are following them). I know that some people like when a lot of people are following them on Twitter, but as for me, I rather know who is following me and wonder why they’re following me. Remember, spam accounts don’t count as followers!
