I followed that.
Some people were publicly upset that "terfs" were "platformed" on Substack. Then lo and behold shortly after, rumors started screaming about "Nazis".
Substack took it seriously, and did an investigation and found 5 accounts with no subscribers which were white supremacist.
I took note of which accounts signed the petition to investigate the Nazis, and unsubscribed from their stacks (I'm only a free subscriber anyway). I don't need to read the gullible.
