FriendFilter (a service of twittFilter) is a new service that helps identify new followers you should follow, and spammers you should block. Here are some ways it will benefit our users:

It sends the auto-email from Twitter when someone new follows you.

It automatically researches additional information about your new followers to help you determine whether or not you should follow them back.

You have the ability to pre-qualify friends based on our FriendFilter score which compares mutual friends and followers, the volume of updates, etc..

Still not sure if you should friend this new follower? Click on the users (or anyones) pic to get a quick view of their latest posts.

~Enjoy!

Sounds great. What does it look like?

Have a look at the image below. That is what you will see in your email. Clicking on any of the icons will give a snapshot will the last 20 messages.

You can also set a minimum score before an email is sent out in case you get a lot of new followers.

You can set this in twittfilter
