Legal Compliance for Global Credit-Based Platform

I'm seeking comprehensive legal guidance for a credit-based content review platform.

I’m building a platform similar to SubmitHub where users (pitchers) purchase credits to submit content for review. Reviewers earn credits for providing feedback, and can later request payouts (e.g. via PayPal or bank transfer).

Key questions:
- Does this setup make the platform an e-money transmitter or require a money services business (MSB) license?
- Are there alternative legal structures (credits, vouchers, etc.) to avoid triggering financial regulations?
- What are the compliance obligations for payouts (EU DAC7, US 1099, etc.)?
- Do reviewers need to be registered as businesses, or can individuals participate legally?
- How should Terms of Service and liability disclaimers be structured to reduce platform risk?
- Any other legal red flags I should be aware of before launch?

Ideal skills and experience:
- Expertise in financial regulations, especially e-money and MSB licenses.
- Knowledge of US and EU compliance requirements.
- Experience drafting legal documents like Terms of Service and liability disclaimers.
- Background in platform-based business models.

Please provide a detailed proposal outlining your approach and relevant experience.
