Quality Control?

Just a question before I get too edit-happy, is there any real standard of quality control for this site beyond the moderation team? It seems like there's very little guidelines to abide by, just that if it's not good it'll be unapproved.

I guess my case in point is the Enchanted Arms page, which has an embedded Penny Arcade cartoon with no caption and is called a summary of the game's reviews. While PA can be biting satire of the industry, it seems rather odd to be right there on the game's page, of questionable relevance, and on many resolutions the width of the image won't play nice with the page formatting.

I had considered deleting this section for being too irrelevant/unfactual and putting a note that said Quality Control so the moderator would know what I was trying to do, but I guess before I try and challenge other people's edits I should ask what the deal here is.
