I checked the logs, and you twice ran the
prune messages function, which deletes all PMs older than x days:
REDACTED - - [05/Aug/2026:00:01:59 +0000] "POST /index.php?action=pm;sa=prune HTTP/1.1" 499 0 "https://bitcointalk.org/index.php?action=pm;sa=prune" "REDACTED" "REDACTED"
REDACTED - - [05/Aug/2026:00:02:04 +0000] "POST /index.php?action=pm;sa=prune HTTP/1.1" 499 0 "https://bitcointalk.org/index.php?action=pm;sa=prune" "REDACTED" "REDACTED"The requests returned the 499 status code, which means that you pressed the "stop" button in your browser. This caused the pruning of your PMs to be interrupted partway through. When your PMs are being pruned, your outbox PMs are deleted first, followed by your inbox PMs. Therefore, I would expect you to also be missing some inbox PMs.
Because this happened recently, and PMs are only ever deleted from the database in a cron job once per week, all of the PMs can be restored.
I can tell you I did not hit prune messages - not sure how that happened then.
@theymos - can you please restore them? -- saw your dm just now and replied.
as a follow up - I checked my pc history and I have never been to the prune page

perhaps it was on my phone? but if I did it - it was a total botch of whatever I was trying to do - I have never deleted any messages except for the ones i accidentally cc myself on and/or the forum ones telling me one of my posts was deleted. will check the phone in a bit.
as a final follow up - I checked my phone browser history and i see that I did indeed visit the prune page - it says the 4th but due to the time difference (-4) the time does match with the time theymos posted

got a dm from theymos - this is now resolved - will lock thread.
