A freelancer stated to me in a message on Upwork that he is part of an agency.
Why would an individual freelancer not disclose that he is part of an agency on his profile?
Is there a rule on Upwork that requires a freelancer to register as an agency?
Freelancers can register as an agency if they are working as a team with 2 or more Freelancers. It is not mandatory for any Independent Freelancer to register as an agency. Feel free to report Freelancer's profile using the 'Flag as Inappropriate' option if they offer to work with an agency but do not have an agency on their Upwork profile.
