I understand where you're coming from about the restriction placed on the account.
As much as we'd love to help, the account you are writing in for has been locked for violating the terms of the
Steam Subscriber Agreement (SSA). The account has been identified as being used for commercial purposes based on its security history, trading activity, community reports, and/or other factors.
Locks of this type are typically issued when the account is bought, sold, traded, or otherwise transferred, or has been used as part of a commercial operation prohibited by the SSA.
The lock is permanent and Steam Support cannot help you further with this.
Because we have provided all the information we have, I am closing this help request. Please note that future help requests submitted regarding the account lock may be closed without a reply.
