I think the Lemmy user you are referring to above got banned, and their posts got removed as the sub-action, but they did not get purge.
Your account got purged on the Piefed instance you linked above.
Now obviously as you can guess it’s difficult to find an example of a purged account on a Lemmy instance as there’s no filter for that kind of actions in the modlog.
Having a closer look at the modlog for diva’s account on quokk.au, it shows “delete user” and not “ban user”, “delete user” being the Piefed version of Lemmy “purge user”
There are two different actions
The documentation explains the difference

TIL, I’m not an admin so I never interacted with that functionality (nor did I rtfm, clearly)
already planning on making a sequel yptb post complaining about being purged

Feel free , at least maybe some other admins can confirm the difference between ban and purge on both platforms 😅
The API has a filter for AdminPurgedPerson, but the result doesn’t include any info on the purged user.
Indeed.
