Opening the blue tick to paying subscribers was among the first decisions made by Elon Musk when he took ownership of Twitter last year, but his overhaul backfired.
Elon Musk has defended his controversial pay model for Twitter, claiming that any social media platform that didn't follow suit would fail because they would be swarmed by bots.
Musk made his prediction on Friday on the eve of Twitter's April 1 ultimatum that verified accounts with the cherished blue tick that had not forked over cash would lose it.
"The fundamental challenge here is that it's (easy) to create literally 10,000 or 100,000 fake Twitter accounts using just one computer at home and with modern AI (artificial intelligence)," Musk told a question and answer session on Twitter.
"That's the reason for really pressing hard on verified where the verified requires a number from a reputable phone carrier and a credit card," Musk said.
"My prediction is that any so-called social media network that doesn't do this will fail," Musk added.
The change in the system puts pressure on companies, journalists and celebrities who used Twitter as their main channel of communication and relied on the blue tick for credibility.
And it also raises the spectre of imposters and jokesters paying for an officially verified, but totally fake account.
In the US, the subscription plan, known as Twitter Blue, costs $8 a month or $84 a year, or $11 a month if bought through Apple’s app store.

Since its creation in 2009, the blue tick or checkmark became a signature element that helped the platform become a trusted forum for newsmakers and campaigners.
But Musk and his fans said the blue check was decided by fiat in a secretive procedure and called it a symbol of an unfair class system.
Opening the blue tick to paying subscribers was among the first decisions made by Musk when he took ownership of Twitter last year, but his overhaul backfired.
Within hours, Twitter was flooded by fake yet verified accounts impersonating celebrities, major companies and even Musk himself.
Musk swiftly backtracked, but many advertisers fled the site, denying Twitter a major source of income that the CEO is struggling to replace.
For now, blue checks of celebrities – including Justin Bieber and his 113 million followers or footballer Cristiano Ronaldo and his 108 million – are tagged on the site as "legacy" accounts.
The verified account conundrum also involves officials, charities and news media companies.
Already the White House, which will keep a special designation as a government entity, told employees it would not pay to have its staff's official Twitter profiles keep the blue tick, Axios reported.
