Research: What compliance challenges have you faced in influencer marketing?

I am a first-time founder of a tech startup applying AI to social media compliance. I am trying to understand the compliance issues in influencer marketing. If you are working in marketing, compliance, regulatory or senior management roles-- what compliance issues have you faced in influencer marketing? -- have you not used some social media channels to avoid compliance issues?-- what tools, if any, do you currently use to deal with social media compliance?I'd love to briefly chat (~20 min) with you to understand your opinions/experiences/advice/concerns. Really appreciate your help. Please dm me or contact me on Linkedin.
