I'm not sure common personal websites are a great analogy to Mastodon... Does your website allows millions of people to interact with each other bidirectionally WHILE being decentralized - in the sense that no single authority can takeover/remove content over ALL the ecosystem? Because that's what Mastodon tries to be. I know that a disproportionately large instance may attract the level of attacks that twitter gets, but - while I'm ignorant of all possible attack vector of activitypub or all mastodon instances - I think it would be hard to take over all those celebrities accounts if they are split among several instances. Each instance admin could potentially try to interrupt the attack on their users on their own. I'm sure ActivityPub and Mastodon are not flawless but I think that if they decentralized in the right way, it does prevent this type of attacks such as the ones witness on Twitter. It's not even through obscurity, it's just through friction of having multiple admins to deal with.
