I'm confused, why would companies be unable to create Polymarket accounts.
By talking about aged accounts and shell companies, I meant that there's black markets for aged accounts from social media platforms, and there's markets for shell companies (and to some extent warmed up emails). In both cases the age of the company gives it some value, as anyone doing due diligence on the accounts will weigh the age of the account as a positive signal.
Age of an account is a costly signal and significantly slows down Sybil attacks. Spammers pay some cost for aged accounts (even if it's just waiting and holding the inventory) and for defenders it works as a PoW system, they don't need to ignore the age signal, it works just fine.
There's just no distinction between accounts like that, 'accounts' are just crypto wallets. There's no system that would ever care about the 'age' of your account here. There's no DD. If you have a wallet, you can participate. The 'spam' prevention measure is the same as for any crypto thing: tx costs.
