This isn't the same type of behavior but I didn't want to start a new thread. I was favorited this morning and as I often do, I clicked on the username to see their bio to know what kind of person it is. I noted that their username was created today. I was curious about whether they created an alt just to favorite me (and get a fresh start hitting on me - it happens) so I looked at their favorite list. 29 stories already - in less than 7 hours of username existence. I wonder what is going on...
Perhaps the person has been a reader for years, and favorited all his/her favorite stories after creating an account for the first time.
That's what I did when I first created my account years ago. I looked for my favorite stories and favorited them.
