I'm not sure how that would have happened as mods who do picture approval are supposed to check to see if the pictures are relevant, but I can say this…
If you see this kind of thing on your torrents, please hit the report button to flag it for the pictures so that mods can correct this for you. I know this isn't the ideal solution for you, but it is an option that we can use with the system as we have it currently. I do understand your frustrations completely. I'm just not sure that the powers that be would be too willing to jump straight to that (just to be honest up front).
