recently Gavin got his audience to mass down vote a community note because it debunked his claims about Anime being pedophilic

Torn on that kind of thing. If Community Notes is vulnerable to mass flagging/voting campaigns then it's an inherently weak system. The line between abuse and legit mass action is unclear. If 4chan anons post about the latest anti-white movie and tell people "you know what to do" is that a troll campaign? No, people are just reporting something they dislike. YouTube has algorithms to silently add/remove votes on videos based on whether they think it's the target of "suspicious activity" i.e. groups of people going there because someone on another site told them to. So what if people do that? I never liked that kind of hidden counter-manipulation based on an assumed problem. Just take the stats as they are and assume the Internet is fake.

It's obviously different if a user is being mass targeted for flagging by people who never even knew the user existed or would have cared about his comments before someone told them to care. That still shows a weakness in the reporting system.
