Reddit shadowban
A Reddit shadowban makes an account’s content invisible to everyone else while it still appears completely normal to the account owner. You keep posting and commenting, you see your own activity exactly where you expect it, and nobody else does. Because there is no notification and nothing looks broken from the inside, a shadowban can run for weeks before anyone realizes it.
How it happens
Shadowbans are typically triggered by behavior that looks like spam to Reddit’s automated systems. Repetitive promotion, posting the same link across many subreddits, link-heavy submissions with little else, and bursts of low-quality activity are the common patterns that get flagged. The systems are pattern matchers, so an account that behaves like the thousands of spam accounts before it tends to be treated like one, regardless of intent.
This is the practical reason credible participation matters so much. An account with real history, a spread of genuine comments, and a normal mix of activity does not resemble the spam profile, so it rarely runs into this in the first place. The behavior that earns standing in a community is also the behavior that keeps an account in good health.
How to check
You can check an account’s visibility with public tools built for exactly this. Sites such as the community-run shadowban checkers take a username and report whether its content is publicly visible. The same check works manually: open a profile or a specific post in a logged-out browser, or in a private window, and see whether the content appears the way it does when you are signed in. If your posts are there while logged in but missing while logged out, that is the signal. This is about confirming visibility, not about getting around a moderator’s decision.
For operators
The takeaway is simple. The way to avoid this class of problem is genuine participation and restraint, not tricks. Contribute more than you take, keep promotion rare and in context, and an account behaves nothing like the spam the filters are built to catch. The full method is in the guide on Reddit marketing for founders, and the credibility that protects an account is measured in Reddit karma.
