payment would need a delay too. Pay $10 and then wait a week or so for the payment to clear without it being reversed. Hopefully that stops the card stealers from dumping as much as possible before getting booted.

Could we just add complex and varied captcha to the comment & posting forms?

That's not a bad idea, sending mail could simply be an authorization for a $1 or $10 charge. And if the receiver said the message was unwanted, then the charge would go through.

There's just the pesky problem of incentives on the other side of the coin - who gets the $? The spammee? But there would be enshitification issues like:

1. Those who are incentivized to take as big a cut as possible.

2. Those who would put it in their EULA that you must accept their spam and not chargeback or else you lose access to something you value like their services (EULA Ransom... not much different to today "accept our EULA or lose access to what you've already paid for!")

I'm sure there are many other perverse incentives which would creep in..
