I suspect the down votes (which I assume you're alluding to) are more regarding the wording. "Got a link that backs up this rather surreal claim?" can read as very aggressive rather than as a genuine question for more information. Also, the second result in my DDG query for "zuckerberg child chinese name" is this link, with the title "Chinese president snubs Mark Zuckerberg’s request for baby name".

Variants of "citation needed", particularly those that appear aggressive and easily searchable can potentially attract downvotes, regardless of the actual intent on the part of the poster, one of the downsides of internet forums where the only channel of communication is the text itself, stripped of intonation and body language.
