Not really. In these areas there's a general principle that the moment you start using a signal to enforce on bad actors that signal's value decays. It's sad, I actually think web3 could help curb abuse at scale by making it too expensive to scale horizontally. Imagine paying a "stamp" to send an email on the blockchain, spam email would dramatically drop. Maybe similar mechanics could be in play for other things but then you lose democratization of information.
What is web3? What exactly is it? And how could it be used in this case?
The idea is you'd have an email client but all data is stored encrypted on chain and you'd have to pay tx costs to send things. By having this sort of stamp tax spammer wouldn't be able to scale mass messaging as it would bankrupt them.
in meatspace though, my real mailbox is mostly filled with spam that the sender paid to have delivered.
granted, it would at least act as a limiting factor.
If you have an auditable tx history, then mixers/exchanges/wallets etc can be marked as sources of the money used by spammers
