Looking at today's reporting, I am seeing more than a handful of clicks from a very remote country at a CTR well above my average (over 20% CTR). These CPC is under 5 cents and they (the clicks have been in the reporting section almost all day). If these click were U.S. clicks they would have been removed from earnings within 2 hours. So, I have to conclude that Google's click fraud algorithm definitely has different rules for different countries and the total of the earnings. Not surprised.
