In other words the idea might have the opposite effect - keeping potential new human users out, but allowing the bots in
The galaxy brain shit here is that I suspect the bot problem actually doesn’t concern Musk in the way he claims. If he can make it seem like there are fewer bots (because of these policies) while at the same time not actually getting rid of them, the engagement level stays up and the advertisers are happy in their ignorance. Bots are better users: they’re not fickle, they don’t go to sleep, they can be reliably expected to be posting more regularly than normal users. The trick for Musk is convincing everyone they’re gone.
Bots aren’t a “problem” for Twitter unless the advertisers think there are more of them than there are real users. But if you can convince advertisers that you’re reducing bots, while also not actually reducing bots, you’ve got a winning formula. Bots are reliable posters, they contribute a lot more than a regular user, and they make high-engagement tweets/posts/tweex that end up getting a lot of views, aka advertising opportunities.
