Checked out some European countries and most seemed to have reasonable results until I got to Iceland. The results from Iceland do indeed suggest the sample set is way too small for some regions.
It seems more likely the results are dominated by searches from one person, especially when there are no results for Slovakians or most of the Balkan states at all.
As for Gay Grandpas, well searching for "Gay Grandpa Sex" [4] yields 29 700 results.
