As has often been pointed out in this forum, non-moderation of a post, even a reported one, does not justify the conclusion that it is within the rules. A few of us mods actually have lives;), and may have been busy or overlooked the report. Unless a mod has positively made a ruling that something is within the rules, you shouldn’t jump to that conclusion.
I would certainly moderate “tard” in any context or combination in GQ if it were brought to my attention.
