Twitter today is introducing a new feature that will allow accounts to self-identify as bots by adding a label to their profile. This feature is designed to help people better differentiate between automated accounts — like bots that retweet the news, public service announcements or other updates — from those operated by humans. It’s not, however, designed to help users identify the “bad bots,” which are those that pose as people, often to spread misinformation or spam.

The company has been contemplating labeling bots for years.
