How do you handle external sharing of assets collected through Deeto or User Evidence?

Hi CMA Community! I'd love to hear this group's perspectives on how you handle the broad external sharing of assets collected by platforms such as Deeto/User Evidence/related platforms - what limitations do you draw regarding how to externally share? If a customer has submitted a quote or testimonial, do you take it to their Comms teams to get formal sign off on publishing on your website or in presentations first? Or do you take their submission as okay to use?
