The number of views should not be considered as criteria for “trending” since a lot of times, the views can come from the wa…z websites.
When your sales drop significantly, check your analytics stats to see your items traffic sources….
Until 23 September I usually had 50 daily visits with approximately 3-4 sales.
From 23 September until today I noticed an important increase in page views (1200 daily visits) but fewer sales.
So I had a look on my analytics stats and surprise: 800-900-1000 daily visits from w…z websites and link anonymize websites.
LATER EDIT: (maybe this is an unfair competition game coming from competitors?)
It happens, indeed, because the trending icon is in a 50px/50px square that overlaps with the icon’s thumbnail icon exactly in that area on top-left.

At a first glance, it seems they are some sort of bots run by people looking to see if your server is running an open proxy which they could use to attack people with.
If you don’t have one already, I recommend the setup of a professional VPS Firewall, these usually make your server invisible to hackers ad protect your admin ports.
