My Steam account is missing some Community features and/or is showing up as a limited user. What does this mean?
CD Keys and retail purchases do not remove limited user restrictions. You must make a purchase from your Steam account or accept a Steam gift.
Limited users are prevented from accessing several features on Steam, including but not limited to:
We've chosen to limit access to these features as a means of protecting our customers from those who abuse Steam for purposes such as spamming and phishing. Spammers' and phishers' ability to send invites and chat requests to strangers is thereby reduced, protecting legitimate users from annoyance and scams.
Other features are still available. Limited users can still create community groups, be added as friends, and chat with other users.
Limited users must navigate to their Steam community homepage in order to view friend requests.
To access all of these features, simply do any of the following on your Steam account: purchase a game from the Steam store (It cannot be a gift for another account), redeem a Steam gift, or complete a microtransaction (in-game purchase).
No. Demos, Free Weekends, free games (Examples: Alien Swarm, free versions of Portal or Team Fortress 2), other promotions do not act as qualifying items.
Steam Support cannot remove this limited user status from your account.
