Someone told me to open here a bug and i didn't see where to click, so i'm using this, i'm sorry.
When a user does something in activity, delete files, etc... And you delete the user, shows the activity as the system's one with the user IP, it's a little bit confusing.
Here is some proof.

Due to

panel/app/Models/ActivityLog.php

Lines 155 to 160 in 3f9c1db

	if (!$user instanceof User) {
	$user = new User([
	'email' => '[email protected]',
	'username' => 'system',
	]);
	}
