There've been some rather high-profile shadowbans (hellban/otherwise you're banned but don't know it) issued against people who did apparently did nothing but publicly state that Pao is a scam artist.

Given that those comments don't actually violate any of Reddit's stated rules, there aren't many other reasonable explanations.

Then again, I called every single one of them liars, publicly, by name, after the recent subreddit closing drama, and I'm not shadowbanned so, who knows.
