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

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.

Click on the time, e.g. `35m`, or the `1 replies`.

How do you see the item number of a comment?

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.
