How exactly does it help when Facebook tells a bad actor what part of the publicly available guidelines were violated? Why can't Facebook just have a hotline/chat that can verify a user's identity and tell them more, preferrable in less than 5 months of spamming their email? And in the case of a permanent ban the user should at least be able to download all their account data; this feature is already implemented for compliance with GDPR anyway and the online platform wouldn't lose anything by at least not making pictures etc. inaccessible forever.
