Should old entries be editable, or does that break the honesty?

Right now you can go back and edit or delete anything you've posted, private or anonymous. Feels right for privacy, nobody should be stuck with something they regret sharing. But it also means every entry can quietly get sanded down into something more flattering after the fact, which is basically the exact self-editing this app exists to get away from.

Torn on whether locking entries after some point is actually more honest, or just adds the same pressure back in through a different door.

How do you think about this?
