How long is a permanent ban on reddit?

The length of a permanent ban on Reddit is indefinite, meaning that it lasts forever and cannot be lifted. Once a user is permanently banned from a subreddit or from Reddit as a whole, they are not allowed to participate in any way, such as posting, commenting, or voting on content. It's important to note that Reddit's content policy and individual subreddit rules are subject to change, so the specific circumstances that could result in a permanent ban may vary over time.
