With respect, EI A330-300, you are now clutching at straws.
The sooner we can accept that these 9,000 passengers were indeed valid passengers, as per the IATA definition, the quicker we can move on.
Whether people feel that these passengers were "fake/pretend/etc" will then be merely a matter of opinion.
As SNN counted them one would assume FR added those 9,000 pax to there traffic figures to.
That is a separate issue, and is not relevant to how SNN counts its passenger numbers.
