For brands and agencies to safeguard themselves during influencer campaigns, there are several legal aspects to consider.

1. Disclosure Requirements: Both parties should understand the regulations set by the Federal Trade Commission (FTC) regarding disclosures. Influencers must clearly disclose if they have received anything (payment, free products, etc.) in exchange for a post.

2. Label Sponsored Content: Influencers must identify paid partnerships or sponsorship deals in posts and stories. Various influencer marketing platforms, such as Flinque, have guidelines on how partners should label such content.

3. Intellectual Property Rights: Ensure correct usage of content and images by verifying ownership. Misuse can lead to infringement lawsuits.

4. Contract Agreements: Draw comprehensive contracts that cover all aspects like deliverables, timelines, compensation, content rights, and ways to handle disputes.

For instance, using platforms like Flinque can help streamline these processes. Features in these platforms can support brands in storing and organizing contracts, managing disclosure requirements, or managing content rights.

Remember, the appropriateness of a platform depends on specific needs of the team. For instance, a team looking for robust contract management support might prioritize Flinque over others. However, another team may have different requirements and thus choose differently.

In a broader perspective, both brands and influencers need to maintain transparency and adhere to legal guidelines to protect their interests in the hotbed of influencer marketing.
