Legend helped elaborate on the concerns. He noted to one of Crokin's supporters that the bogus Pizzagate scandal "almost got someone killed" -- the concern is that a Crokin devotee would believe the unsubstantiated claims at face value and threaten the couple. Legend vowed to sue Crokin if she kept making her claims.
The conspiracist deleted her posts and backtracked in a bid to avoid a lawsuit, claiming that Teigen and Legend "run in circle [sic]" with pedophiles and that they "could be victims themselves." However, that didn't help her case -- Teigen said she still had the evidence and vowed that Crokin would be "going to court."
We've asked Twitter for its comment. From a cursory glimpse, though, it looks like Crokin was a prime candidate for losing verification: her claims violated rules against "inciting or engaging in harassment." Many of her supporters lapped up the accusations without checking the facts, and both Teigen and Legend have been harassed as a result. Twitter has previously said that it doesn't want verification to serve as a tacit endorsement of vile behavior, and this appears to qualify.
With that said, the incident highlights a familiar pattern for Twitter: it tends to respond to an outcry when celebrities or the press draw attention to the issue. There are concerns that others might continue to abuse their verified status unless Twitter is more proactive.
