Quotes restricted it to exact whole word matches; no fuzzy matches (Fukishima) nor any "as root word" matches, F-ed, F-ing, F-ery, F-ers, etc.

As an Australian I'm not sure how I feel about one of our more expressive words being described as a bomb and singled out, but I'll take the badge with pride.

This shows up as zero for me but the badge site says I've used it twice. It's pretty easy to manually check since I haven't made too many comments. I suspect the badge site is fuzzy matching since "luck" or some variation has appeared twice (now three times)
