Please don't change subjects. We were talking about "shadowbanning", not Hunter Biden. Twitter has stated for years that they have controls to prevent algorithmic recommendation of particular users, content, or trends, and that's precisely what we saw reported on by Taibbi and Weiss. They had direct access to Twitter internals and did not report any "shadowbanning" functionality. It's fair to assume that they would have reported it if it existed.
No, I don't think it's understandable for Musk to respond to someone stalking him by modifying Twitter policies to retaliate against another person with no connection to the stalking.
