K: Hello again and, again, thank you for your response to my question. Your comment is appreciated.
As far as I can determine, the 2016 profile had not been touched during the almost eight years since its creation, and was an 'orphan profile' (of one of my distant relatives) when I adopted it. Thus my curiosity, and question.
I had, perhaps wrongly, assumed that the profile being an 'open', 'orphan' profile without a PM nor, presumably, a 'trusted list' (though I've yet to determine who or what creates such a list in the first place) nor any contributions since its creation, would not have warranted a 'sticker' being added. Thus my curiosity, and question.
Perhaps I should simply contact the 'sticker' contributor directly?
