[Meta]People not labeling their characters in this sub

Redditors - This sub

Can we please make it an enforced rule in this sub to label the characters one comments? It's extremely annoying to have interesting posts, just for them to be filled with meaningless screenshots, because not everyone knows every fictional character. I know there is a similar rule for posts, but if there is one for comments as well, it does not seem to be enforced at all.
