Earlier quoted context omitted.
Why would Twitter reject $10,000 coming out of one credit card? The economic incentive of this model is backwards. A person paying $10,000 for 10,000 bot accounts is a bigger source of revenue than a $1 normie.
You think they’re making money on $1 per account? Processing fees will eat most of that. It seems likely to me they’re doing it to improve the user experience, which if that recruits more users will be worth much more to them than the 10,000 bots each paying $1/year.
Bonus points: bots want the blue-checkmark to look more legitimate, so bots are also more likely to pay $8/month for the blue checkmark. The actual revenue is going to be far higher in practice when you consider that any bot-farm / astroturf will obviously have some blue-checkmarks + an army of normies in some kind of mix.
