Hi, Group Recruitment isn't for promoting a curator.

Group Recruitment
In this category you are allowed to promote your Steam group, corresponding group giveaways and events, and relevant products or services (e.g. a website with group information or statistics). One of the primary aspects of your group needs to be SteamGifts or gifting using our platform.

In fact promoting a curator is frowned upon:

Directly naming or linking to an associated product or service will always be viewed as advertising. General references (e.g. referring to your "website", "YouTube channel", or "Steam group") may also be viewed as advertising when we believe their purpose is to bring attention to an associated product or service for publicity or sales.
