With all due respect, this doesn’t answer the question. Actually, it makes the latest trend look even weirder and statistically impossible.
The trend in the latest months is clear: many of the featured authors have just signed up and many of the featured items have just been released.
It would be good to have a confirmation that this clear trend is an actual criterion that the Quality Team takes into account when selecting a new featured author or a new featured item. Because, if that is the case, instead of releasing a new item under my 9-year-old account, I would create a new account and release the new item with that.
I am under the impression that some new users might be veterans who create new accounts just to fall into this trend. It took me 5 years to perfect how to format an item description, how to use the dashboard tools proficiently, how the affiliate program works. Some of these new users get all that right out of the box, in just a few weeks.
So, bottom line, if this trend is not a coincidence – it would be very unlikely, from a statistical point of view –, we would like to know.
