How many times in the last 2-3 years has facebook claimed there was no problem with something, and then later changed their story? Off the top of my head I can think of at least two instances where they blatantly miscounted the amount they charged advertisers for paid traffic they never sent, and that's without even getting into zuck's wild claims that fb had zero effect on the 2016 election, and then months later admitting that was completely wrong. There is very little reason to trust 'facebook releasing numbers' on this issue. They have EVERY reason to obfuscate, stall, and misreport on it - they are complicit in an extremely serious federal crime.
