Too ambitious for her own good, or addicted to publicity. Although yes, it is possible it was staged. But if she is still alive she is really probably too addicted to publicity to stay hidden for the rest of her life, so if any new "influencer" who looks like her surfaces in the next months, or few years latest, well, considering how internet works somebody will presumably find it.

Or somebody will tell. They ended up telling about that "Ghost of Kyiv" not too long afterwards too, presumably because too many internet sleuths figured it was a fake.
