That’s all well and good, but if you think that Facebook isn’t mirroring all data from the Fediverse, and any other network it can touch, and then correlating what it can back to whatever individual/digital/personal profiles it can, you’d be mistaken.
The only solution here is a political one with significant judicial punishment as the enforcement mechanism. FYI I’m also including the guillotine in the list of nonviable solutions, as the problem is too large and geographically vast to behead our way out of it, even if it would be cathartic.
