When you delete, you delete the pre image. The hash is still timestamped, viewable, and verifiable.
Eg if I say something regarded, you can store the pre image yourself if you’d like, and prove to people it was said when it was said regardless of its deletion status.
Note from the preimage in some cases someone could brute-force the deleted message. You could fix this by creating a 128-bit nonce for every item and including that nonce in the hashed data - OpenTimestamps itself does to prevent the OTS calendars from learning anything about what is being timestamped.

Correction: from the hash digest of course. Not the preimage. That doesn't need bruteforcing!

Outstanding!
