What is Account age on Reddit?
Account age is how long ago your Reddit account was created, and many communities require a minimum before you can post.
The anniversary of your account is called your cake day. Reddit shows a small cake next to your name on that day each year.
Communities use age and karma together as a simple way to keep out spam accounts made yesterday.
If you are promoting something
A new account cannot be rushed. Use the first weeks to read, comment and learn. Do not buy or borrow an old account, because that is against Reddit's rules and people notice.
