Can you link a reliable source for this? The only thing I could find online was someone claiming this with a chart that does not refer to Afd at all.
One of the reasons we need to better relate social media companies, is so we can get at this data. Twitter was incredibly open, pre-Musk. If you're running a platform like that, you're a publisher, and should be required to provide API access for accountability and transparency purposes.
As far as I can tell there is no reliable data that would indicate any of that.
