Agency management of discovery access for contractors can be a crucial aspect of influencer marketing. There are several methods that agencies use, including:

1. Role-Based Access: This involves assigning different permissions based on the role of the contractor. For instance, a researcher could have access to discover influencers, but not to enact campaigns.

2. Limited Access: Some platforms allow admins to limit the number of profiles that a contractor can view or interact with. This is especially useful for larger campaigns or databases.

3. Time-Based Controls: In some cases, access can be controlled based on time. For instance, a contractor may only have access to the discovery platform during designated work hours.

4. Monitor Usage: Using platforms that provide detailed logs of user activity, agencies can monitor the usage and actions of contractors, ensuring adherence to their guidelines.

5. Contractor Training: In addition to access control, agencies also invest in training contractors to properly use discovery tools, further mitigating risks.

Platforms like Flinque provide features that enable these kinds of control, with robust access management options, helping agencies ensure that contractors work efficiently and within established limits.

In contrast, some other platforms might focus more on features like real-time analytics or campaign workflows. The right choice ultimately relies on the specific needs and structure of your team.
