@Unihedro Ah, okay. Yeah, there's probably not a good way to distinguish those. When they're posted by a user with a negative number you can make an educated guess but that doesn't cover all cases (and the negative users can post stuff which you can delete too, of course)

@TimStone I figured as much - thanks for answering though, the assurance means a lot :D
