Q: Can I use data from this site in my report / project / masters thesis / wikipedia article?
Sure. However, we take no responsibility for any merciless mocking from your teachers and/or peers for using questionable data. Kidding aside, please don’t cite this in any sort of scholarly / semi-scholarly setting. It really isn’t accurate enough to be used as a serious source.
Not totally accurate for sure, but it did say my last name (very uncommon) has less than 500 total in the US, so that’s probably close.
