Keep what is needed. Remove what is not.

Deletion exceptions
A deletion request does not require removal where continued processing is lawfully necessary, for example to comply with a legal obligation, establish or defend a legal claim, protect another person's rights, preserve a serious safety investigation, or prevent documented fraud or block evasion. Any exception must be specific, proportionate, access-restricted, documented, and reviewed. It is not a reason to keep an entire account indefinitely.
Anonymous information
Statistics that have been irreversibly anonymised so no person is identifiable may be kept to understand service reliability, county coverage, moderation workload, and safety trends. Pseudonymous identifiers and hashed network context are still treated as personal data where they can be linked back to a person.
