Over the last few days I’ve pursued my idea to build a “Twitter spammer detector” of sorts using only client-side technologies. I didn’t feel like setting up server components at all.
What was it supposed to do? It should check the number of followers of everyone on your contact list, the number of people they are following, and the ratio between those. If the person is following more than 1000 people (can be customised), and has a Following-to-Followers ratio higher than 1:1 (can be customised), you’d be informed (by a handy “Block” link).
