What is "flair" in a Reddit community?

Flair on Reddit refers to customizable tags that users or moderators can apply to posts or usernames within a specific community (subreddit). These tags help categorize content, making it easier for users to distinguish different types of posts (e.g., "Question," "News," "Discussion") or to identify specific user roles (e.g., "Moderator," "Original Poster"). Flair improves content organization and discoverability, allowing users to filter posts based on their interests. It is not a user's avatar (which is their profile picture), a voting option (which is upvoting or downvoting), or a type of advertisement (though ads may use flair for categorization).
