I don't think it was calculated at all. It's highly likely this was just a few lines adding "gun/rifle/revolver/etc." to the blacklist of forbidden search terms for that service. It's the same list containing terms like "child porn" and as long as one of the file owners approves the CL it goes into production immediately. I really doubt this went through a regular launch process and had an Ariane bit flipped as part of a proper review.
