I'm not fully aware regarding what type of questions are well-received in this site, and I could not provide a reliable source for my question (instead, I was looking for it).
So I added a question to the chat, if someone could help me there.
[EDIT for further cases like this:
I finally posted my question, which is this one, and my doubts regarding this question's fitness in the site were these:
- I read the claim long time ago. Quite long time ago.
- I cannot remember most of the details, except those stated in the question.
- I cannot find a reference to a reliable source. In face: I was asking if such reliable source existed.
And since this is one of my first questions on the site and am not sure how this site operates]
