WHY IT NEEDS A POLICY

Why quote_tweet needs a policy

Quoting a tweet creates new public content on Twitter by wrapping an existing tweet with commentary. This is a Write operation as it creates new data on the platform. While reversible in theory (the quote tweet could be deleted), the primary action is content creation. Severity is medium because misuse could post unwanted public content at scale, but it's not irreversible by nature.
