Pages last modified by unknown user

Hello experts,

I would like to fetch the page that is last modified by the unknown user. I couldn't find a way. Please provide me some solution.

Hi @Dabin Daniel Sundaram  - not sure if this is helpful, but I needed to get a list of pages assigned to unknown user, and this was content I used

Hi @Ami Chitwood

Thank you for your response.
I have two requirements:
1) I need the username of last modifier of the page which is created by the unknown user. - Last modifier of the page which should be the user who actually edited but the query in the KB which you have shared is displaying the creator(unknown user) as the last modifier which is not correct. You can check this with your data.
2) I need the username of the page which is last modified by the unknown user.

For the above two requirements I couldn't find any KB from the Atlassian.

Regards,
Dabin
