This is happening because at least one user from your instance is a moderator for the community. This issue has been reported previously to us in matrix. Here is the relevant issue on codeberg. I have previously tried to figure out what is causing this to happen to no avail. It seems like whenever PieFed tries to send a report to a moderator, lemmy will also send it to the admins on that instance.
Maybe if @rimu@piefed.social gets a chance to dig into this some more, he can figure out how to prevent the reports from escalating to admins when they should stay at the mod level.
