What are Twitter users who subscribe to another user's posts called?

Twitter users who subscribe to another user’s posts are called followers. A follower is an account that has chosen to follow another account, allowing the followed account’s posts to appear in the follower’s Home timeline. After Twitter’s 2023 rebrand, X continued using the same term.

The word followers describes a one-way relationship, not necessarily a friendship or mutual connection. If Alice follows Bob, Alice is Bob’s follower, while Bob appears in Alice’s following list. Bob does not have to follow Alice back. This distinction was one of Twitter’s defining differences from social networks built mainly around mutual friend connections.

Followers may receive notifications about new posts depending on their settings, and they can see public posts from accounts they follow. Protected accounts work differently: a person must be approved before becoming a follower with access to protected posts. Users can also remove or block followers, while the platform’s follower count records how many accounts currently follow a profile.
