TwitBlock is a junk filter and bulk blocking tool for Twitter. It scans your followers for nuisance accounts and makes it easy to block them all in one place. You can also see who you're already blocking; something you can't do on twitter.com.
How many people follow you on Twitter? How many do you listen to? Friends and Followers, mutual friends, for so many it seems to be a numbers game. I have far more Twitter accounts than is healthy! Admittedly these are for business, clients or pet projects but yesterday I received a lot of what looked to be spam followers. Now my thinking in the past has been, well they won't be listening to anything I say but it's a follower. I had no intention of following these back but then I realised it dilutes the quality of my following. I have always been very proud that I can flick through my followers with a pretty good idea why I picked most of them up. Some I know, some I admire, some I want to meet, some I want to work with, many have attended events I have twitter curated and followed me from there and there are many good friends who I don't see half as much as I would like.
It found 35 bots in 850+ followers and to my delight only 1 in my friends and that was one of my own pet project which was dormant! So... How about you?
