Can Coinbase refund if scammed?

Could you please clarify if Coinbase offers a refund policy in the event that a customer falls victim to a scam? I understand that cryptocurrency transactions are irreversible, but I'm wondering if there are any measures Coinbase has in place to protect its users from fraudulent activities and if they can provide any form of compensation in such cases. Additionally, are there any best practices that Coinbase recommends for its users to prevent scams and safeguard their digital assets?
