What are "new-user restrictions," and how do they protect communities?

New-user restrictions are a collection of limitations that Reddit applies to recently created accounts, designed to reduce the effectiveness of spammers, bots, trolls, and ban-evaders while allowing legitimate new users to gradually earn full participation rights. These restrictions operate at two levels simultaneously: platform-wide restrictions set by Reddit itself, and community-specific restrictions set by each subreddit's moderators. At the platform level, accounts that are very new — typically less than a week old — face limits on certain social actions such as starting direct chats, following other users, and may have their posts automatically held for moderator review in certain communities rather than appearing immediately. Reddit's anti-spam systems apply more aggressive automated filtering to posts and comments from new accounts, meaning a new account's content is more likely to be caught in spam filters even when it is entirely legitimate. At the community level, moderators can configure AutoModerator to automatically remove, filter, or flag posts and comments from accounts below a specified karma threshold or account age. When a new user's post is caught by these filters, it does not appear in the community feed until a moderator manually approves it, or it is simply removed without the user being notified (which can be confusing for newcomers). The protective logic is layered: requiring time and karma investment before gaining full access raises the cost of operating fake, spam, or harassment accounts significantly. A troll who is banned from a subreddit under one account cannot immediately return under a fresh account and cause the same damage, because the fresh account will lack the karma and age needed to post freely. These restrictions do create friction for genuine new users, which Reddit acknowledges, but the platform views that friction as an acceptable trade-off for the spam and harassment reduction it achieves.
