I guess the counter (which I think you're pointing out) to that is to publish text to a known-trusted website rather than a video, but I wonder how many folks who get their "news" from TikTok would read it.
By "verified", I assume Twitter has verified that their identity on Twitter matches their real life identity, and I don't see a problem with anyone having an ability to claim that. What's wrong with Jane Random being verified that she _is_ Jane Random?
If people are basing their trust not on someone's identity and history, but on their celebrity (blue mark so far), that's where the problem is.
They then spoof being the real person, and verification then means absolutely nothing cause they are functionally identical to a bypasser.
By having verification be really hard to get, trolls have a lot harder time getting accounts and the problem is smaller in scope.
Having initial validation accessible is not the issue here.
It's like allowing verified emails to be changed to another address without reverifying.
I mean, doh.
