this is just the orchestra getting warmed up. Meta (and other companies) know there is no meaningful accountability for these kinds of fuck ups in a country that's too corrupt to have functional regulators or pass a modern privacy law
I would be completely unsurprised if Zuck purpose built this URL architecture exactly so he, and anybody who pays him for it, can access all of this information.
Much as I loathe those "and this surprises you???" replies, seriously. In a sane universe Meta would be buried under lawsuits and have literally no users.
