A simple command line tool to unfollow inactive accounts.
const unIn = require('unfollow-inactive');
//get your keys at https://apps.twitter.com/
const authObj = {
consumer_key: '<your_consumer_key>',
consumer_secret: '<your_consumer_secret>',
access_token_key: '<your_access_token_key>',
access_token_secret: '<your_token_secret>'
}
unIn(authObj);
On the actual version the utility just logs friends which have not set a status since 1 year to the console.
