The good news is that this should definitely reduce the volume of bot / troll accounts, by making it prohibitively expensive to run. That will mean a reduction of disinformation on aggregate - as what other purpose would there be to run a bot network? The bad news is that it recreates the lords vs servants dynamic that Musk is claiming to want to get rid of. $8 is not much for everyone reading on HN, but guess what,…
$8 won’t necessarily price out spam accounts. As a counter example, on Tinder there are many fake/spam accounts with premium membership.
I don't know how the financial transactions & stuff work in the background, but the point is that you have more information and more options.
