We've had multiple people prominent enough to make the front page of hacker news in the last few months. Maybe we should get some statistics on how many people are prominent enough and controversial enough to land on the front page of hn, then work back to how many of their millions of customers are actually affected. Its probably a lot more than just 1.
Yes, I suspect so. What it takes, arguably, is being just controversial enough to attract complaints and/or attention from algorithms. But not famous enough for a ban to attract huge attention in mainstream media.
