This is not a security or anti-bot proposal. It's a revenue proposal. Lots of $1 fees = lots of $. His statement is a rationalization and nothing more.
If he wanted to run a platform where bots weren't a problem, all he needs to do is to have all accounts (new and old) be associated with an actual individual's verified gov't ID, a business or a gov't institution. No more anonymous accounts, none. Can you imagine how much that would cut down on the racism, the misogyny, the antisemitism, the hate posts, the trolling, the bots, the ads, the hookers, the illegal activities, the misinformation, all of the stuff that makes Twitter/X junk.
But Musk doesn't want to do that. He wants lots of accounts, and lots of engagement, so he's going to keep all the bad stuff along with the good, and that includes the bots. Because bots cause clicks and engagement, and he wants to show advertisers that he has clicks and engagement.
My Twitter/X account has my real name. My picture. My employer's name. And guess what, I don't troll or say stupid ***t on there. I would love it if Twitter/X was completely verified, real people/organizations that spoke publicly and freely but they couldn't hide behind internet anonymity.
And yes I realize the irony that I am posting from a MR account that isn't my real name, that's obvious. If MR asked us to lose our anonymity in the forums, I would.
