Sometimes some posters don't have an id inside boards where every poster has ids
and it also appears that in the moderation pages those id-less posters have no informations, unlike other posters who do, so those id-less posters are immune to some moderation actions

is it a feature for some posters to be id-less?
or is it a bug?
regardless if it's a bug or not, this is a weakness in the moderation tools, is there any way to resolve this?
