Reddit USL Check is a free Chrome add-on developed by mraahz and built by ThunderPowa. This add-on enhances the user experience on Reddit by adding a USL (Universal Scammer List) tag after usernames displayed on the platform. The tag provides valuable information about the user's status, indicating whether they are currently banned or safe.

With Reddit USL Check, users can easily identify potential scammers or problematic users on Reddit. By clicking on the USL tag, it instantly changes color to either green for "Safe" or red for "Banned," providing a quick visual reference for user status. This feature helps users make informed decisions when engaging with other Reddit members.
