Most of the ads above/below the games themselves come from Google, so if you've browsed a lot of Spanish sites, then Google ads will appear accordingly.
One way to stop it is to log out of your Google account before coming to Armor Games, then Google will more likely anonymize your ads.
Thank you for the quick response. However I never browse Spanish sites. Also this seems to be the only site afflicted. Odd. I now know more about Tide in Spanish than English. Not really a huge deal. Just confusing.
