In what situations do experienced users create throwaway accounts?

A throwaway account is a Reddit account created for a specific, time-limited purpose, with the expectation that the user will not maintain it as an ongoing identity afterward. The throwaway convention emerged from Reddit's culture of pseudonymity and is most commonly used when someone wants to discuss something sensitive under an identity that is completely disconnected from their main account. The most common situations where experienced users create throwaways include: asking questions about medical symptoms, mental health conditions, or substance use that they do not want associated with their primary Reddit identity; sharing personal confessions or difficult experiences (infidelity, addiction, abuse, legal trouble) in communities where anonymity is considered appropriate; posting NSFW or adult content in communities that allow it, under an account separate from their main identity to avoid that content appearing in their profile history; and whistleblowing or sharing information about an employer, institution, or individual that might create professional or legal risk if traced back to them. Some subreddits — particularly those dedicated to support around sensitive topics like relationship abuse, addiction recovery, or sexual health — explicitly encourage users to post via throwaway accounts and even instruct users to include "throwaway" in the username so moderators understand the context. Throwaway accounts face the same new-user restrictions as any other new Reddit account, which has made them less practical over time as karma and age requirements have increased. Some communities have adapted by allowing posting without meeting minimum requirements if the post is clearly a throwaway on a sensitive topic and is submitted for moderator review. Experienced Reddit users sometimes create and lightly use a throwaway for weeks before needing it, precisely to build enough karma to clear posting restrictions.
