Federal privacy commissioner Philippe Dufresne and commissioners in Alberta, British Columbia and Quebec found TikTok failed to keep Canadian children off its platform and collected vast amounts of personal information, including information considered sensitive.
“The investigation uncovered that TikTok removes approximately 500,000 underage users from the platform each year,” said the report. “Where these children were engaging with the platform before being removed, TikTok was already collecting, inferring and using information about them to serve them targeted ads and recommend tailored content to them.”

TikTok was caught using biometric information via facial and vocal analytics. It did not adequately explain to users that their data would be used to infer age and gender for the delivery of tailored ads and recommended content.

Nothing’s been done about it because the oligarchs who own every political class, in every country, are using big data and analytics to wage psychological warfare and infect the global population with a sort “disinformation psychosis”, “broke mind virus”, etc … corrupt societies logic and mental health so significantly they can enslave us, rob us blind, use us for cannon fodder, etc, etc.
Representative democracy is the only threat to their wealth and power, so their goal is to exterminate it.
Mentioning TikTok, but not every American social media app is dishonest. Trumps fascist oligarchy can’t pretend to be the goodguys as they send the military against their own peaceful civilians.
