How do you see where you've been banned or muted?

Reddit does not provide a centralized dashboard that lists all the communities from which you have been banned or muted, which means the primary way users discover their bans is through the notification system rather than by looking up a list proactively. When a subreddit moderator bans you, Reddit automatically sends a private message to your Reddit inbox from the subreddit's modmail system. This message indicates that you have been banned from the community, may include the reason given by the moderators, and may specify whether the ban is temporary or permanent. If you receive no explanation, you can reply to the ban notification to ask the moderators for a reason, though they are not required to provide one. Similarly, if you are muted by a subreddit (prevented from sending modmail to that community), a notification is sent informing you of the mute and its duration, typically 28 days. If you attempt to post or comment in a community from which you are banned, Reddit will display an error message indicating that you have been banned from that subreddit, which is another way users discover bans they may not have been notified about (for example, if they missed the inbox notification). To review your ban notifications after the fact, you can search your Reddit inbox for messages from modmail. There is a third-party tool approach that some users use: because ban notifications are sent as private messages, they remain in your inbox indefinitely unless you delete them, so scrolling through old modmail messages provides a historical record. There is no official Reddit page that aggregates all ban statuses in one place, which is a frequently requested feature in Reddit's feedback communities. For platform-wide suspensions and shadowbans, the reddit.com/appeals page remains the official checking mechanism.
