For some reason a couple of videos have become extremely popular on our video channel, and surpass any other videos in views by an order of magnitude (almost...).
Our most popular videos are generally hit in the same range (12,000-15,000, maybe 18,000 views), but one single video has more than 130,000 views according to its counter! The second most viewed has more than 25,000 hits when this is written.
I haven't been able to see any real strange traffic patterns or anything really odd in our statistics for these two videos, but I still suspect that something isn't quite kosher because even though both videos are fine, they are surpassed in quality (and viewer's votes) by numerous other videos on the site. The Dorado video get a ton of hits from Brazil and Argentina, but that's no surprise. Still the number is a surprise. 99% of our Brazilian visitors see this video and nothing else... The traffic to these two videos has also peaked a long time ago, and these days they are not nearly as popular as they were. Signs of something fishy, robot visits, traffic spamming or whatnot.
So I have decided to rule them out per the statistician's tool: "remove odd results", a method commonly used when results in a group are extremely different.
