This doesn’t work in perpetuity. One of the reason why spam is so persistent is that when you ban a spammer, they can just create a new identity and go again. If payment is required then not only do they have to repeatedly pay every time they get banned, they need a new payment card too because you aren’t limited to banning their account – you can ban the payment mechanism they used.
This is only to the point that it’s not profitable to spam further.
At some point your cost to dissuade spammers becomes a huge risk for humans to make mistakes of any sort.
At this point users mutiny.
Users don’t typically get banned repeatedly, and you probably want the ones that do to stay banned.
