OAI and Anthropic both require KYC for models of similar intelligence. They both do account bans if the classifiers fire wrong. You simply hear about it less with OAI because Codex has fewer prosumers.
Can you name any instance of OpenAI being as trigger-happy with bans as Anthropic has been in the past few months? Codex may have fewer prosumers, but they've added a lot in that time.
There will obviously be more reports about Anthropic because hating on Anthropic has been trendy lately, it has more users, and gullible people (including most HN'ers) fall victim to OAI's guerrilla marketing.
In terms of bans and KYC they are not meaningfully different.
