As a manager with access to management chat, where this was happening (as the system was essentially made by grim) I can say that if this is a thing, it wasn't intentional. I'm not quite sure how it was done, but notes were removed that contained IP addresses. The actual notes themselves should still be on their record though, it's just a case of gpanel not loading them.
We still check the notes before accepting a mod. If note removal is occurring, it's not an intentional thing, as it'd be logged and other staff members could see us doing it. There's a log generated when someone deletes notes.
