I’m proud of Twitter.

Last year they started taking action to reduce the amount of spammers on their network.  As a free service, they are the target of abuse attacks.  Yet in the beginning, it’s not something that most services need to worry about.  It’s only when you start to become popular that you start to attract the ilk of the spammer.

If you’ll check out that blog post, then by their own internal metrics Twitter has reduced the spam volume of spammy posts/tweets from 10% in August 2009 to close to 1% today.  That’s incredible:

Reducing abuse on a free service like this is notoriously tricky, but it looks like Twitter has managed to implement a number of security measures designed to cut down on malicious sign ups and malicious posts and has demonstrated notable progress.
