You're missing the most important detail of why that worked. Forcing payment solves issues surrounding identity. Permabans on other platforms don't work when you can make a new email and sign up again. Sure, there's a cost to bans ($10) but it's minimal, but evading a permaban means finding a new means of payment not linked to your identity which is a lot harder. Not impossible, but enough that it stops most bad actors.
