Project mention: Vitalik on Community Notes | news.ycombinator.com | 2023-08-28

Post-Elon takeover the amount of bot spam I encounter has definitely decreased. I'm not sure the claim of Twitter moderation is accurate, since before the takeover the problem was still present.
The problem got so bad in YouTube Comments that eventually third-party tools [0] were developed to help purge spam.
I agree that if you had a team monitoring spam they could write rules to drastically reduce spam. It's always going to be a cat and mouse game, but if the cat side was more proactive it would definitely lead to a better experience.
